Analysis of Follicle Stimulating Hormone Receptor Gene Mutation in Korean

Premature ovarian failure is a condition causing amenorrhea, hypoestrogenism, and elevated gonadotropins in women younger than 40 years. Many causes of premature ovarian failure were reported, including genetic abnormalities, enzymatic defects, defects in gonadotropin secretion or action, autoimmune disorders, physical and idiopathic causes. Recently, Finnish group reported a point mutation in the follicle stimulating hormone (FSH) receptor gene in premature ovarian failure patients. But it was reported that the group from United States could not find any mutation in FSH receptor gene. So we analysed C566T point mutation of FSH receptor gene using restriction fragment length polymorphism (RFLP) and compared the result between premature ovarian failure patient with idiopathic and known causes. But we did not find 556C${\rightarrow}$T mutation in the FSH receptor gene in both groups. These findings suggest that the missense mutation in the human FSH receptor gene reported in Finnish women with premature ovarian failure is uncommon in Korean women with premature ovarian failure.
