摘要: 特发性低促性腺激素性性功能减退症(idiopathic hypogonadotropic hypogonadism, IHH是一种以内源性促性腺激素释放激素(gonadotropin-releasing hormone, GnRH)缺乏或作用缺陷为特征的罕见内分泌疾病,主要临床表现为性腺功能障碍。IHH患者根据是否合并嗅觉障碍分为两大类:伴有嗅觉受损者称为卡尔曼综合征(Kallmann syndrome, KS),嗅觉正常者称为嗅觉正常的IHH(normosmic IHH, nIHH)。本文报道了115岁男性,表现为第二性征发育迟缓,相关检查提示存在低促性腺激素水平的低睾酮血症且嗅觉正常,诊断为nIHH。高通量基因测序提示该患者存在NSMF:c.79C>G(p.Arg27Gly)基因突变,该突变位点既往国内外文献中尚未报道。通过总结该患者临床特点及对NSMF基因新变异进行分析丰富了NSMF基因变异谱,并为该类疾病的临床精准诊疗提供了临床资料和遗传资源

Abstract:

Idiopathic hypogonadotropic hypogonadism (IHH) is a rare endocrine disorder characterized by deficiency or dysfunction of endogenous gonadotropin-releasing hormone (GnRH), leading primarily to hypogonadism. Based on the presence or absence of olfactory dysfunction, IHH is classified into Kallmann syndrome (KS) and normosmic IHH (nIHH). In this study, we reported a 15-year-old male with nIHH, presenting with delayed puberty, hypogonadotropic hypogonadism and normal olfaction. High-throughput gene sequencing identified a novel NSMF:c.79C>G (p.Arg27Gly) variant which has not been reported in the previous literature. By summarizing the patients clinical characteristics and analyzing new NSMF gene variant, this study enriches the mutation spectrum of NSMF gene and provides clinical data and genetic resources for the diagnosis and treatment of IHH.
