Mendelian trait/disorder: yes

Mode of inheritance: Autosomal recessive

Considered a defect: no

Key variant known: yes

Year key variant first reported: 2018

Cross-species summary: Long hair = angora

Inheritance: Yu et al. (2018): "This mutation was genotyped by direct sequencing analysis in 141 short‐haired and 70 long‐haired individuals. We found 104 homozygous CC and 37 heterozygous CT short‐haired individuals, whereas all long‐haired individuals were homozygous TT, indicating that the long‐haired phenotype is inherited as a recessive trait as in other mammalian species."

Molecular basis: By sequencing the obvious comparative candidate gene, Yu et al. (2018) discovered a likely causal variant for long-haired guinea pigs to be "a nonsense mutation (c.403C>T, p.Arg135Xaa) in exon 2 [of FGF5] . . . , which leads to a truncated protein of 134 amino acids."

Genetic engineering: Unknown
Have human generated variants been created, e.g. through genetic engineering and gene editing

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.
