OMIA 000439-9838 : Hair, long in Camelus dromedarius
Maraqa et al. (2021) "developed a fast qualitative approach to estimate hair length in camels by photographing a splayed hand pressed onto mid-torso hair during the peak of hair growth" and used a candidate gene approach to identify a missense variant that is associated with hair length.Molecular basis: Maraqa et al. (2021) used a candidate gene approach to identify a c.779C>T, p.(P260L) mutation in the FGF5 gene that is associated with hair-length variation. The authors sequenced the FGF5 gene in 28 animals from several breeds of dromedaries (Mejaheem, Shaele, Sofor, Waddah and Omani) and validated the association of the identified c.779C>T variant with hair length in additional camels (n = 113, including 5 trios). Animals with short hair were homozygous for the C allele, animals with intermediate hair were heterozygous and animals with long hair were homozygous for the T allele. Prevalence: Maraqa et al. (2021): "The allele frequencies were 0.525 and 0.149 for (C) and (T) respectively." 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.
