It is now recognized that female carriers of fragile X premutations are at increased risk of premature ovarian failure. We have studied 51 premenopausal women from fragile X families, to determine whether premutation carriers have variations in the hormonal markers of menopause, compared to full mutations and controls. We found a significant increase in serum follicle stimulating hormone in premutation carriers, suggesting that as a group they will enter menopause before full mutation carriers and unaffected controls. These results have important implications for fertility in these women.
现在人们认识到,脆性X前突变的女性携带者过早卵巢功能衰竭的风险增加。我们研究了来自脆性X家族的51名绝经前女性,以确定前突变携带者与完全突变者和对照组相比,在绝经激素标志物方面是否存在差异。我们发现前突变携带者的血清卵泡刺激素显著增加,这表明作为一个群体,她们将比完全突变携带者和未受影响的对照组更早进入更年期。这些结果对这些女性的生育能力具有重要意义。
