OMIA 001559-9940 : Fecundity, Embrapa, FecG(E) in Ovis aries

Possibly relevant human trait(s) and/or gene(s) (MIM number): 601918

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal

Considered a defect: no

Key variant known: yes

Year key variant first reported: 2011

Molecular basis: Silva et al. (2011) reported a missense mutation (c.1034T>G; p.Phe345Cys) in the GDF9 gene giving rise to increases of 82% and 58% for ovulation rate and prolificacy, respectively, compared with homozygous wild-type.

Breed: Embrapa.

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.
