Cross-species summary: Long hair = angora

Molecular basis: Daverio et al. (2017): "All animals analyzed were homozygous for one of the . . . [two likely causal variants, namely the haplotype comprising c.348delA and c.351_352insCATATAACATAG, or the [nonsense] variant c.499T] or compound heterozygous for both (i.e. c.348delA, c.351_352insCATATAACATAG/c.499T). Sequencing of guanaco samples showed that the FGF5 gene encodes a full-length 270-amino acid protein. These results suggest that FGF5 is likely functional in short-haired wild species and non-functional in the domestic fiber-producing species, the llama". Noting that the haplotype variant results in "a putative truncated protein of 123 amino acids" and the nonsense variant "leads to a premature stop codon at position 168", and "Sequencing of guanaco samples showed that the FGF5 gene encodes a full-length 270-amino acid protein", Daverio et al. (2017) concluded that "These results suggest that FGF5 is likely functional in short-haired wild species and non-functional in the domestic fiber-producing species, the llama".

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.
