Cross-species summary: This is a type of XY difference of sexual development (XY DSD) due to variants in the NR5A1 gene. The gene is also called SF1.
Species-specific name: XY difference of sexual development, NR5A1-related; XY disorder of sexual development, NR5A1-related
History: Nowacka-Woszuk et al. (2020): "This is the first mutation in the NR5A1 gene leading to XY DSD phenotype to be reported in domestic animals."
Molecular basis: Nowacka-Woszuk et al. (2020) reported "a large deletion consisting of four exons of the NR5A1 gene was identified in a Yorkshire Terrier with a rudimentary penis, hypospadias, bilateral cryptorchidism, and spermatogenesis inactive testes."
Breed:
Yorkshire Terrier (Dog) (VBO_0201448).
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).

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.
