The acyl-coenzyme A synthetase long-chain family member 6 (ACSL6) gene on chromosome 5q31 was associated with premature ovarian failure and identified disease-susceptibility haplotypes.
ADAMTS19 expression is higher in the murine embryonic ovary than in the embryonic testis during sexual differentiation, and an ADAMTS19 SNP (rs246246) showed a possible association with POF in a genome-wide association study in Caucasian women.
Although limited by sample size, this proof-of-principle study's findings reveal ADAMTS19 as a possible candidate gene for POF and thus a larger follow-up study is warranted.
We propose that microdeletions within FMR2 may be a significant cause of premature ovarian failure, being found in 1.5% of women with the condition, and in only 0.04% of the general female population.
These results indicate a pivotal role for NUP107 in ovarian development and suggest that nucleoporin defects may play a role in milder and more common conditions such as premature ovarian failure.
In this study, we postulated that the patients with premature ovarian failure, which has been reported to be linked with X-chromosome abnormality, have AT(2) receptor mutation that may contribute to the early onset of atresia.
We have cloned the mouse AT2 receptor gene (Agtr2) and determined its map position by linkage analysis using an interspecific backcross (C57BL/6J x Mus spretus).Agtr2 is located on the proximal mouse X chromosome between DXMit85 and DXMit49, in a region of conserved synteny with a part of the human X chromosome implicated in inherited forms of premature ovarian failure.
StCA were present in 22 of 38 with APS-1 (57.9%) (11 of 13 with POF); in five of 13 with APS-4 (38.5%) (three of four with POF); in 53 of 162 with APS-2 (32.7%) (17 of 26 with POF), and in one of 28 isolated AD patients (3.6%).
Autosomal disorders such as mutations of the phosphomannomutase 2 (PMM2) gene, the galactose-1-phosphate uridyltransferase (GALT) gene, the FSH receptor (FSHR) gene, chromosome 3q containing the Blepharophimosis gene and the autoimmune regulator (AIRE) gene, responsible for polyendocrinopathy-candidiasis-ectodermal dystrophy, have been identified in patients with POF.
One of the patients, a woman with Addison's disease, autoimmune thyroiditis, and premature menopause was heterozygous for a point mutation (G1021A, Val301Met) in the first plant homeodomain zinc finger domain of the autoimmune regulator (AIRE) gene.
The homologous human region has been precisely identified as an HSA 3q23 DNA segment containing the Blepharophimosis Ptosis Epicanthus locus (BPES), a syndrome combining Premature Ovarian Failure (POF) and an excess of epidermis of the eyelids.
