OMIA 002229-9940 : Hypotrichosis, HR-related in Ovis aries
Category: Integument (skin) phene
Links to MONDO diseases: No links.
Mendelian trait/disorder: yes
Mode of inheritance: Autosomal recessive
Considered a defect: yes
Key variant known: yes
Year key variant first reported: 2003
Cross-species summary: Also known as Hairless
Species-specific name: Absence of all or part of the wool coat
Mapping: Using FISH, Finocchiaro et al. (2008) physically mapped the HR locus in sheep to chromosome OAR2p21-22.
Molecular basis: By cloning and sequencing a very likely comparative candidate gene (based on the homologous human and mouse disorder), Finocchiaro et al. (2003) discovered the likely causal variant to be a nonsense mutation, namely "a C/T transition at position 1312" of the ovine HR gene, giving rise to p.Gln438Ter.

By default, variants are sorted chronologically by year of publication, to provide a historical perspective. Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column headers.
WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.
Since October 2021, OMIA includes a semiautomated lift-over pipeline to facilitate updates of genomic positions to a recent reference genome position. These changes to genomic positions are not always reflected in the ‘acknowledgements’ or ‘verbal description’ fields in this table.
