Task: Answer Verification
Input (English): Question: Is age at natural menopause linked with the follicle-stimulating hormone receptor region : a sib-pair study?
Answer: Possibly, age at natural menopause in the more or less normal range is not part of the spectrum of phenotypes determined by mutations in the FSH-receptor gene. Alternatively, our results might be explained by genetic heterogeneity in the left tail of the distribution of menopausal age. This can limit the chance of finding a genetic locus, especially if this factor has a modest contribution to the phenotype.
Output (English): no
