OMIA 002230-9913 : Hypotrichosis, HEPHL1-related in Bos taurus
A full account of the discovery by Kuca et al. (2021) included details of the likely causal variant, namely chr29: g.721234A>T; c.1684A>T; p.Lys562*.Clinical features: Kuca et al. (2021): "On clinical examination, the Swiss calf was found to be clinically healthy except for the skin abnormalities. Particular clinical examination of the cardiovascular, respiratory, genitourinary, musculoskeletal, and nervous systems showed no abnormalities. Moreover, no abnormalities in dentition were noticed as previously seen in cattle affected by ectodermal dysplasia characterized by sparse hair and abnormal teeth . . . . The integumentary system examination revealed multiple small to large areas of alopecia on the limbs and the dorsal part of the head, neck, and back . . . . The largest alopecic lesions were located on the lateral and medial aspects of the tarsal joints and the dorsal aspect of the fetlock and carpal joints. Moderate scaling was also present on the dorsal aspect of the head and neck. Excoriations were also present on the dorsal aspect of the fetlock and carpal joints and the lateral aspect of the tarsal joints. There was no evidence of erythema, pruritus, crusting, or thickening of the skin." Breed: Belted Galloway. Associated gene:

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.
