Mutations in the NOG gene are not a common cause of nonsyndromic premature ovarian failure

Premature ovarian failure (POF) is clinically defined as at least 6 months of amenorrhoea and elevated plasmatic levels of FSH in women below the age of 40 years. It affects about 1% of women under 40. 1 POF has been described to be associated with autoimmune diseases, pelvic surgery, chemotherapy, radiotherapy, infectious agents and environmental factors. In some cases, genetic causes have been identified. They include X chromosomal alterations (i.e. Turner Syndrome) and mutations in autosomal and X-linked genes. 1
