ORANGE LOCUS AND VARIANT UNCOVERED!!:
Two preprints (Toh et al. and Kaelin et al.), uploaded to bioRxiv on consecutive days, have reported the long-awaited discovery that that Orange locus in cats is the X-linked gene ARHGAP36; and that the Orange variant, responsible for the Garfields of this world (as well as, of course, tortoiseshells and calicos), is a 5.1kb deletion in the first intron of ARHGAP36. See the OMIA entry for more details, including a brief history of this phene. [posted 28 November 2024]
omia.variant registered in Bioregistry:
The prefix 'omia.variant' is now registered with Bioregistry, an open source, community curated registry, meta-registry, and compact identifier resolver. The prefix 'omia' had been registered previously. See https://bioregistry.io/registry/omia.variant and https://bioregistry.io/registry/omia for details. Compact URIs (CURIEs) can now be constructed for OMIA variants, e.g. omia.variant:1710.
HAPPY 29th BIRTHDAY OMIA!:
With many thanks to all the people over all those years (see Acknowledgements), who have made this possible.

SERVER UPGRADE COMPLETED!:
The OMIA server upgrade has been completed! We apologise, again, for OMIA being out of action for several hours.
OMIA NOT AVAILABLE FOR 5 HOURS:
A major server upgrade will take place this Thursday 17 April, starting at 4pm (AEST) and lasting for up to 5 hours! We have chosen this time so as to have the least impact globally. We regret this outage, but have been assured it is essential.
OMIA information enhances comparative medical genomics:
A paper just published by human geneticists in Toronto, Canada, led by Greg Costain has shown that pathogenic missense variants in OMIA provide useful indications of the likely pathogenicity of comparable human variants (same gene, same peptide residue). The authors conclude: “These results provide further support for comparative medical genomics approaches that connect big data initiatives in human and veterinary genetics.”
HAPPY MENDEL DAY:
Today we celebrate the anniversary of Mendel completing the reading of his paper to the Natural Science Society in Brno in 1865. OMIA has assembled information on the Pioneers of Mendelian Inheritance in Animals, viewable under the OMIA PMIA tab. [Posted 8 March 2024]
OMIA VERY SLOW!!!:
If you are reading this notice, you will know that OMIA is SERIOUSLY SLOW !! We apologise for this, and are doing everything possible to resolve the problem. [Posted 2.01 pm Sydney time 1 Feb 2024]
The problem has been resolved [Posted 6.28 pm Sydney time 8 Feb 2024]
Revised summary table on home page:
On 16th January 2024 a revised summary table on the OMIA home page was launched. In creating this revision, the aim was to provide summary statistics for all Mendelian traits (diseases and non-diseases) and for the subset Mendelian diseases. If you see anything that needs to be changed or that could be further improved, please email [email protected]. Thanks to Jørgen Agerholm for suggesting the need for an enhanced summary table.
Giraffe with no spots: OMIA entry awaiting results!:
Many OMIA users will have seen that the spotless giraffe born on 31 July in Brights Zoo, Tennessee, was yesterday given a name: Kipekee. Imke has created a new entry in OMIA for this phene in giraffes (https://omia.org/OMIA000200/9894/). We assume that someone somewhere is already investigating whether there is a likely causal variant for this phene. If there is, we look forward to entering it in OMIA. (posted 7 September 2023)
Reporting likely causal genotypes from sequencing data:
Boeykens et al. (BMC Bioinformatics (2023) 24:305) have created an R-package called VariantscanR that uses a table of likely causal variants downloaded from OMIA (or created manually) to interrogate VCF files from “whole genome sequencing (WGS) and whole exome sequencing (WES)” of an individual animal. Among other outputs, the package reports the genotype of the animal at every locus for which a likely causal variant has been reported, thereby facilitating the choice of mating pairs in the control of inherited disorders.
Origins: a scientific creation oratorio:
On 18th July 2023, as a feature of the 23rd International Congress of Genetics in Melbourne, the world premiere of a scientific oratorio took place in the Melbourne Recital Hall. The libretto, written by geneticist and long-time chorister Jenny Graves, with help from poet and fellow chorister Leigh Hay, was set to music by composer Nicholas Buc. The oratorio tells the same story as Haydn's marvellous oratorio, Creation, but from a scientific point of view. Jenny Graves explains Origins here. [posted 19 July 2023]

The black swan:
A recent paper has moved us one step closer to the likely causal variant for the black swan. Intriguingly, it is possible that this totem of rareness is actually homozygous for a fully functional variant of the pigment-related SLC45A2 gene; and that the common white swan is homozygous for a frame-shifting deletion that inactivates the role of the SLC45A2 gene. Read all about it at https://omia.org/OMIA002617/8868/. [posted 27 January 2023]
TRIBUTES TO ROY ROBINSON:
Professor Leslie Lyons has provided a wonderful tribute to Roy Robinson, viewable by going to the PMIA tab, and searching for Robinson. Other tributes would be welcomed. Please email them to [email protected]. Posted 17 Dec 2022.
ROY ROBINSON was born 100 years ago today!:
Today (14 Dec 2022) we pay homage to the enormous contribution made to our knowledge of Mendelian inheritance in animals by the self-educated, self-employed Roy Robinson. His many scientific papers and books were published over nearly five decades from 1951 to 1998 (two years after his death). Some of his books are still in press today, and one of them has been given the ultimate accolade of a new edition written by other authors with the title “Robinson’s Genetics for Cat Breeders and Veterinarians”. Very insightful information on Robinson is provided by Sarah Hartwell at http://messybeast.com/retro-genetics-robinson.htm. For more information on Roy, go to the PMIA tab and search for Robinson.
OUTAGE MONDAY 5th DECEMBER 2022:
For many years, it has been realised that the home-grown OMIA breed list needs to be replaced by a computable comprehensive list of breed names, including all synonyms. The development of the Vertebrate Breed Ontology (VBO) to fill this need is described in the OMIA Acknowledgments page. To install VBO, which is a major enhancement for OMIA, there will be an outage of OMIA next Monday 5th December, for up to one hour, starting at 11am Eastern Standard Daylight Time. For equivalent times elsewhere, see: https://www.timeanddate.com/worldclock/fixedtime.html?iso=20221205T110000&p1=240
HAPPY 200th BIRTHDAY (AGAIN!), MENDEL:
Today (22nd July) is the second of two possible Mendel birthdays; the one favoured by his mum, and hence by Mendel. In their introduction to a set of PNAS bicentenary papers on Mendel published on 18th July (https://www.pnas.org/doi/10.1073/pnas.2201327119), Leif Andersson (a major contributor to OMIA), Nils Stenseth and Hopi Hoekstra provide background to this intriguing question.
HAPPY 200th BIRTHDAY, MENDEL!:
Today (20th July) is the first of two possible Mendel birthdays, the other being 22nd July. Mendel favoured the 22nd. However, in their introduction to a set of PNAS bicentenary papers on Mendel published two days ago (https://www.pnas.org/doi/10.1073/pnas.2201327119), Leif Andersson (a major contributor to OMIA), Nils Stenseth and Hopi Hoekstra weighed all the evidence, and decide that today is the day!
Pioneers of Mendelian Inheritance in Animals (PMIA):
With just two weeks to go to the bicentenary of Mendel's birth, OMIA today has launched a series of commentaries on the early discoveries of Mendelian inheritance in animals. They can be accessed via the PMIA tab here on the OMIA home page. Over the next few months, additional commentaries will be added. [posted 8th July 2022]
HAPPY MENDEL DAY!:
In this Mendel bicentenary year, today we celebrate the anniversary of Mendel completing the reading of his paper to the Natural Science Society in Brno in 1865. As part of the bicentenary celebrations, OMIA is assembling information on the Pioneers of Mendelian Inheritance in Animals. Today initial posts have been sent to AGDG and angenmap. Some of this information is being incorporated under the OMIA Landmarks tab; other information will be mounted elsewhere in OMIA (soon to be announced). [posted 8 March 2022]
Happy DARWIN DAY!!:
Darwin day marks the anniversary of his birth on 12 Feb 1809. Darwin Day is the first of three days over three consecutive months, highlighting major breakthroughs in biological understanding. Consistent with the chronology of discovery, Darwin Day is followed by Mendel Day on 6th March and DNA Day on 25 April. As it happens, Darwin celebrated his 27th birthday in Australia. The house (Secheron) in which he dined that evening in 1836 still stands in Battery Point, Hobart. [posted 12 Feb 2022]
Happy new Mendel anniversary year!:
As many of you will know, 2022 is the bicentenary of Mendel's birth, on 20th (according to his birth certificate) or 22nd July (according to Mendel and his family) in 1822. 2022 is also the centenary of the birth (on 14 December 1922) of Roy Robinson, a pioneer of Mendelian inheritance in animals. OMIA will join many others in marking both these anniversaries this year.

HAPPY 25th BIRTHDAY, OMIA!:
On 26th May 1995, OMIA was launched on a server hosted at the University of Sydney. The 25th anniversary virtual celebration was announced in a webpage that provides links to three videos. Sincere thanks are due to the many people who have enabled OMIA to function and grow over these 25 years. They are named and thanked under the OMIA Acknowledgements tab. Their invaluable contributions are much appreciated.
HAPPY MENDEL DAY 2020!:
Yesterday (8th March; I missed it by a day!) marks the 155th anniversary of Mendel completing the reading of his paper to the Natural History Society of Brünn (Brno in the Czech Republic) in 1865. Mendel Day sits symbolically between Darwin Day in February and DNA Day in April, neatly replicating the chronology of three of the most important discoveries in biology.
OMIA is fundraising:
From 18 March 2019, users will see a fundraising popup once a month when they access this website. The popup is also viewable anytime from the Donate tab on the home page. OMIA's venture into this form of fundraising follows that of OMIM (on which OMIA is modelled) which has been conducting a popup-fundraising scheme since 2016. It is hoped to raise sufficient funds to retain a part-time software engineer for maintenance and enhancements, and (in the longer term) to retain a part-time head curator when Frank Nicholas is no longer able to fulfil that role.
ANOTHER OMIA UPGRADE!:
Yet another major upgrade of OMIA was launched on 14th November 2018. The new version reflects a comprehensive upgrade of the computing infrastructure, including establishment of a secure https protocol. It also includes a text-mining tool for curators that will greatly enhance the efficiency of curation. The tool starts with daily PubTator annotations of PubMed abstracts, and then feeds selected abstracts into a pipeline that includes a taxonomy filter and screening by a machine-learning classifier. The result is around 5 PubMed IDs being deposited into the OMIA publication curation tool each day, from the approximately 5000 new abstracts added to PubMed each day. The upgrade also includes a few specific enhancements, such as presenting the results of all searches in tabular form. Due to illness of the software engineer who developed these specific enhancements, some of them (including the tables) are not yet fully functional.
HAPPY MENDEL DAY!:
Today (8th March 2018) marks the 153rd anniversary of Mendel completing the reading of his paper to the Natural History Society of Brünn (Brno in the Czech Republic). Mendel Day sits symbolically between Darwin Day in February and DNA Day in April, neatly replicating the chronology of three of the most important discoveries in biology.
A NEW VERSION OF OMIA!:
OMIA has two new features: 1. a new URL (http://omia.org) (the old one redirects to the new one)
2. sortable tables of likely causal variants in (more-or-less) standard format. For more details, see the user guide available from the Help tab.
MENDEL DAY: 8th March 2017:
Professor Eva Matalova and her colleagues in the Mendelianum in Brno have arranged a wonderful program for Mendel Day 2017, including a guided walking Mendel tour of Brno; an exhibition; a concert of violin music of Leos Janacek, who, as a former organ scholar in Mendel's monastery, arranged the music and played the organ at Mendel's requiem mass; and (on 9th March) a trip to Vienna for a tour of sites associated with Mendel's student days. For details see the Mendelianum website.
First large-scale screening of disease-implicated variants across purebred dogs:
By genotyping of 6,788 dogs from 233 breeds for 93 disease-implicated variants across 80 single-locus disorders, Donner et al. (2016) have provided a very informative "snapshot" of the distribution and frequency of these variants across breeds. Among other things, the results indicate that certain disease-implicated variants occur in more breeds than was previously thought.
Reverse genomics reveals genetic load:
In a landmark project, Michot et al. (2016) analysed the genomic sequence of 1147 bulls (representing 15 European breeds) from the 1000 bull genome project, yielding "2489 putative deleterious variants (stop lost and gained, frameshift, splice acceptor and donor sites, initiator codon variants and missense variants predicted as deleterious with a score of 0 by SIFT) that segregated at a frequency of 5 % or more in at least one of the 15 breeds represented by at least 20 genomes in run 4 of the 1000 bull genomes project". As a proof-of-principle illustration of the nature of these variants, Michot et al. (2016) "investigated the phenotypic consequences of a frameshift variant in the retinitis pigmentosa-1 gene segregating in several breeds and at a high frequency (27 %) in Normande cattle . . . [that] causes progressive degeneration of photoreceptors leading to complete blindness in homozygotes". See OMIA 002029/9913
The genetic basis of evolution in Galapagos finches:
In some ground-breaking research showing the enormous potential of whole-genome sequence data in "unmapped" species, Leif Andersson has teamed with Peter and Rosemary Grant and other colleagues to identify two genes that have played a major role in the evolution of beak shape and beak size in the so-called Darwin finches of the Galapagos Islands. See OMIA 001945-48881 and OMIA 001992-48881.
HAPPY MENDEL DAY!:
Today (8th March) marks the 151st anniversary of Mendel completing the reading of his paper to the Brno Nature Science Society; a paper that, without Mendel ever realising it, paved the way for our ever-increasing understanding of life on earth. On this day we should also remember the English biologist William Bateson, who, in 1900, was the first person to fully comprehend the universality of Mendel's hypothesis, and who, as described in the Landmarks tab of this website, rapidly demonstrated this universality in animals.
Mendel Day: 8th March:
To mark the 150th anniversary of the publication of Mendel's paper in the journal of the Nature Science Society in Brno, Professor Eva Matalova and her colleagues in the Mendelianum in Brno have proposed that 8th March be celebrated as Mendel Day. The March timing of Mendel Day symbolically fits between Darwin Day in February and DNA Day in April, neatly replicating the chronology of three of the most important discoveries in biology. Geneticists around the world are encouraged to mark this event. Details are available from the Mendelianum website.
An ancient 'supergene' with profound effects on male breeding behaviour, body size and plumage colour:
The ruff is a Eurasian shorebird that has a spectacular lekking behaviour where highly ornamented males compete for females. On 16 November 2015, two groups have simultaneously reported that males with alternative reproductive strategies carry a chromosomal rearrangement that has been maintained as a balanced genetic polymorphism for about 4 million years. (text based on a press release from Uppsala University)
HAPPY 20th BIRTHDAY OMIA!:
On 26th May 1995, the online version of Mendelian Inheritance in Animals first went public, signalling the birth of OMIA. Details of the history of OMIA, and of its predecessor MIA, including mention of many people who have been involved over the years, are available under the Acknowledgements tab just above this notice.
MENDEL SESQUICENTENARY!!:
Exactly 150 years ago, on 8 February and 8 March 1865, Johann (Gregor) Mendel read his paradigm-shifting paper Versuche über Pflanzenhybriden (Experiments on Plant Hybridization) to the Natural History Society of Brünn (Brno in the Czech Republic), reporting the results of eight years of experimental crosses among different (inbred) varieties of the garden pea, Pisum sativum. The paper was published the following year in the proceedings of the Society (Verhandlungen des naturforschenden Vereins Brünn). The original paper (in German) and an English translation (based on C. T. Druery's original translation done for William Bateson) are both available online: German; English.
Third and final chicken comb gene resolved:
19 March 2015: Dorshorst et al. (2015) have reported the molecular basis of the third of the three classic comb types in chickens. This third type (Duplex) turns out to be due to a large (20kb) "duplication . . . located 200 Kb upstream of EOMES, a gene that was found to be abnormally expressed in the comb-developing region of Vshaped and Buttercup comb chicken embryos". As the authors also report, "These findings complete our characterization of the genetic basis of the three major comb loci in the chicken, all of which are caused by large-scale structural genomic variants that drive ectopic expression of transcription factors in the comb region during chicken embryo development".
Haplotype tests for recessive disorders that affect fertility and other traits:
31 October 2014: USDA researchers J.B. Cole, P.M. VanRaden, D.J. Null, J.L. Hutchison, T.A. Cooper, and S.M. Hubbard have summarised the latest information about haplotypes affecting fertility and other traits in cattle on their Animal Improvement Program website. Their table contains hyperlinks to relevant OMIA entries.
OMIA mirror at NCBI decommissioned:
16th April 2014: NCBI has decommissioned its OMIA mirror, due to funding constraints. All OMIA traffic to NCBI is now redirected to this home site. All OMIA links to NCBI remain functional from this home site. Discussions are underway for the establishment of links to OMIA from various relevant NCBI resources.
Review of OMIA causal/key variants:
26 December 2013: An open-access review of the discovery of causal/key variants in non-laboratory animals has been published in Animal Genetics.
Balancing selection at the polled/horns locus:
21 August 2013: A fascinating evolutionary story concerning the polled/horns locus in Soay sheep has been uncovered by Johnston et al. (2013). This has all the hallmarks of a classic textbook example of heterozygote advantage (overdominance) for fitness.
Manx taillessness resolved:
15 August 2013: Buckingham et al. (2013) have reported mutations in the T gene that are causal for the various short-tail phenotypes characteristic of Manx cats. Short tail in Manx cats was the first feline trait to be documented as Mendelian (by Bateson in his 1909 book "Mendel’s Principles of Heredity"). Mutations in the homologous genes in dogs and mice give rise to similar phenotypes.
DNA tests for canine and feline hereditary diseases:
In February 2013, a new web site was launched to provide up-to-date information on the availability of DNA tests for canine and feline single-locus disorders. For background, see Slutsky et al. (2013) Veterinary Journal
Key locomotion mutation identified:
On 29 August, in a paper in Nature, Andersson et al. (2012) reported a nonsense mutation in DMRT3, which encodes a transcription factor, that plays a major role in determining mode of locomotion. For more information, and access to a copy of the paper, see Gaitedness.
Two iconic Mendelian traits resolved in a week! :
One hundred and ten years after they were first described as Mendelian (single-locus) traits, the last two of the six originally-described Mendelian traits have been resolved (or partly so) at the molecular level within a week of each other! On 21 June 2012, Medugorac et al. (PLoS ONE 7(6): e39477) described two bovine alleles (both complex indels) that are completely associated with Polledness in cattle of European origin. One week later (28 June 2012), Imsland et al. (PLoS Genet 8(6): e1002775) reported two chicken alleles (a very large (7.38Mb) inversion and another complex rearrangement derived from that inversion) that give rise to the Rose-comb phenotype in chickens. The chicken inversion results in "the relocalization of the MNR2 homeodomain protein gene leading to transient ectopic expression of MNR2 during comb development". Mysteriously, neither of the bovine polled alleles disrupts "any known coding sequence or a splice site, or an intronic region, or any known regulatory regions". Posted 30 June 2012
Vale Alan Wilton:
Among many other things, Alan Wilton was a very active and highly-regarded member of the global research community devoted to identifying the causal mutations for inherited diseases in dogs. He died on 14th October 2011, aged 58, still in his intellectual prime. His publications in canine inherited diseases were concerned with Cerebellar abiotrophy, Neuronal ceroid lipofuscinosis 5, Neuronal ceroid lipofuscinosis 8, and Trapped Neutrophil Syndrome. For the second and fourth of these disorders, he was instrumental in discovering the causal mutation. As a colleague and friend, he is sorely missed.UNSW tribute
