Year key variant first reported: 2021

Molecular basis: Braun et al. (2021): "Filtering whole genome sequencing data revealed a private frameshift variant within the candidate gene ZIC2 in the affected calf. . . . A 1-bp deletion (g.80722845TC>T; ARS-UCD1.2:g.76742066TC>T) in exon 4 of the candidate gene ZIC2 . . . was heterozygous in the affected calf and homozygous wild type in both parents and all other Limousin herdmates and private controls. . . . The origin of this variant is most likely due to a de novo mutation in the germline of one parent or during very early embryonic development."

Breed: Limousin (Cattle) (VBO_0000274).
Breeds in which the phene has been documented. (If a likely causal variant has been documented for the phene, see the variant table breeds in which the variant has been reported).

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.
