OMIA 001350-9940 : Fecundity, Hanna, FecX(H) in Ovis aries

Possibly relevant human trait(s) and/or gene(s) (MIM number): 300510

Mendelian trait/disorder: yes

Mode of inheritance: X-linked

Considered a defect: no

Key variant known: yes

Year key variant first reported: 2000

Species-specific symbol: FecX(H)

History: The first report of this gene for fecundity was by Davis et al. (1994, 1995).

Mapping: As reported by Davis et al. (1995), "Crossing FecXI with FecXH animals produces FecXI/FecXH infertile females phenotypically indistinguishable from FecXI/FecXI females", suggesting that FecXI and FecXH are allelic at a single X-linked locus.

Molecular basis: Armed with the strong assumption that FecX(H) is allelic with FecX(I) (see Mapping section above), and having identified BMP15 as a strong comparative positional candidate gene for FecX(I), Galloway et al. (2000) showed that the causative mutation for FecX(H) is a "single C→T transition at nucleotide position 67 of the mature peptide coding region of FecXH carriers [which] introduces a premature stop codon in the place of glutamic acid (Q) at amino-acid residue 23 (residue 291 of the unprocessed protein) . . . Such premature truncation probably results in complete loss of BMP15 function."

Breed: Romney Marsh.

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.
