Description : Premature ovarian failure is clearly a heterogeneous disorder. The terms 'hypergonadotropic ovarian failure' and 'hypergonadotropic ovarian dysgenesis' (see ODG1, 233300) have been used to indicate a group of disorders in which amenorrhea associated with elevated levels of serum gonadotropins occurs long before the age of 40 years (Coulam, 1982). Cytogenetic studies of X-chromosome aberrations have suggested that it is mainly the long arm of the X chromosome that is involved in defects of ovulation (Bione et al., 1998). - Genetic Heterogeneity of Premature Ovarian Failure Mutations in genes identified within a region defined as POF2 (Xq13.3-q21.1) have been found to cause other forms of POF: POF2A (300511) by mutation in the DIAPH2 gene (300108) and POF2B (300604) by mutation in the POF1B gene (300603). See also POF3 (608996), which can be caused by mutation in the FOXL2 gene (605597), POF4 (see 300510), which can be caused by mutation in the BMP15 gene (300247), POF5 (611548), which can be caused by mutation in the NOBOX gene (610934), POF6 (612310), which can be caused by mutation in the FIGLA gene (608697), and POF7 (612964), which is caused by mutation in the NR5A1 gene (184757).;

Inheritance : X-linked;

Molecular basis : Caused by mutation in the FMR1 gene (FMR1, 309550.0004);

Prefixed ID : #311360;
