摘要
双倍性 IGFALS 变异会导致酸性亚基(ALS)缺乏症,其特征是生长激素抵抗,伴有或不伴有青春期延迟。在此,我们报告了一名青春期前的男孩,他的第四个 N-糖基化基团(c.1103_1108del, p.N368_S370delinsT)中存在 2 个氨基酸的同源缺失,且与父母血缘关系有关。他的身材矮小,与 ALS 缺乏症一致。该病例扩大了 IGFALS 的突变范围,包括只消除 ALS 的一个 N-糖基化位点。
Homozygous 6-bp deletion of IGFALS in a prepubertal boy with short stature.
Biallelic IGFALS variants lead to acid‒labile subunit (ALS) deficiency characterized by growth hormone resistance with or without delayed puberty. Here, we report a prepubertal boy with a homozygous 2-amino acid deletion within the fourth N-glycosylation motif (c.1103_1108del, p.N368_S370delinsT) associated with parental consanguinity. He showed short stature consistent with ALS deficiency. This case expands the mutation spectrum of IGFALS to include the elimination of only one N-glycosylation motif of ALS.
