OMIA:002017-9685 : Glaucoma 3, primary congenital in Felis catus (domestic cat) |
Categories: Vision / eye phene
Links to possible relevant human trait(s) and/or gene(s) in OMIM: 613086 (trait) , 602091 (gene)
Links to relevant human diseases in MONDO:
Single-gene trait/disorder: yes
Mode of inheritance: Autosomal recessive
Disease-related: yes
Key variant known: yes
Year key variant first reported: 2016
Mapping: As reported by Kuehn et al. (2016): "Using a candidate gene approach, significant linkage was established on cat chromosome B3 (LOD 18.38, θ = 0.00) using tightly linked short tandem repeat (STR) loci to the candidate gene, LTBP2."
Molecular basis: Kuehn et al. (2016): "A 4 base-pair insertion was identified in exon 8 [at chrB3: 120995236] of LTBP2 in affected individuals that generates a frame shift that completely alters the downstream open reading frame and eliminates functional domains".
Clinical features: Kuehn et al. (2016): "Elevated intraocular pressure, globe enlargement and elongated ciliary processes were consistently observed in all affected cats by 8 weeks of age. Varying degrees of optic nerve damage resulted by 6 months of age. Although subtle lens zonular instability was a common feature in this cohort, pronounced ectopia lentis was identified in less than 10% of cats examined."
Pathology: Kuehn et al. (2016): "glaucoma in this pedigree is attributed to histologically confirmed arrest in the early post-natal development of the aqueous humor outflow pathways in the anterior segment of the eyes of affected animals."
Breed:

Variants
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.
