OMIA 000426-9913 : Gonadal hypoplasia in Bos taurus

In other species: sheep

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Recessive

Considered a defect: yes

Key variant known: yes

Year key variant first reported: 2013

Cross-species summary: Incomplete development or underdevelopment of the gonads (testes or ovaries).

Species-specific description: This disorder is associated with white coat colour (Lauvergne, 1970).

Mapping: By conducting a GWAS on 21 affected and 75 control Northern Finncattle and Swedish Mountain cattle, each genotyped with the Illumina BovineHD SNp chip (yielding 647,971 informative SNPs), Venhoranta et al. (2013) mapped this disorder to chromosome BTA29. Further testing identified a 2.81Mb region between 17.69 Mb and 20.50 Mb. A copy number variant (CNV) analysis identified "a CNV segment on BTA6, extending from 71.60 Mb to 72.13 Mb and containing the KIT gene" and another on BTA29, but both of these were thought to reflect associations with the extent of white coat colour rather than the disorder.

Molecular basis: Aware that the molecular cause of colour-sidedness in cattle (OMIA 001576-9913) results from reciprocal translocation between segments on chromosomes BTA6 (containing the KIT gene) and BTA29, Venhoranta et al. (2013) built on their mapping results (above) with cytogenetic and PCR analyses, and concluded "that homozygosity of a ~500 kb chromosomal segment translocated from BTA6 to BTA29 (Cs29 allele) is the underlying genetic mechanism responsible for gonadal hypoplasia. The duplicated segment includes the KIT gene that is known to regulate the migration of germ cells and precursors of melanocytes. This duplication is also one of the two translocations associated with colour sidedness in various cattle breeds."

Breeds: Northern Finncattle, Swedish Mountain.

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.
