伴有减数分裂停滞的人类特发性非梗阻性无精症(NOA)的遗传原因仍不清楚。两个不孕不育的中国家庭参与了这项研究。在家庭 1 中,两个兄弟患有特发性 NOA。在家庭2中,先证者被诊断患有特发性NOA,他的姐姐患有不孕症。对家族 1 中的两名患者、家族 2 中的先证者以及另外 362 名散发性特发性 NOA 患者进行了全外显子组测序 (WES)。 Sanger测序用于验证WES结果。通过高碘酸-希夫 (PAS)、免疫组织化学 (IHC) 和减数分裂染色体扩散分析来评估受影响病例中精子发生停滞的阶段。我们在来自家族 1 的两例 NOA 受影响病例中鉴定出了 SHOC1 的复合杂合功能丧失 (LoF) 变异(分别为 c.C1582T:p.R528X 和 c.231_232del:p.L78Sfs*9)。在家族 2 中,在 患有不孕症的兄弟姐妹。 PAS、IHC 和减数分裂染色体扩散分析表明,三名 NOA 患者的精子发生在受精卵阶段被抑制。与常染色体隐性遗传模式一致,所有这些 SHOC1 变异体均遗传自杂合父母携带者。有趣的是,362 例散发性 NOA 病例的 WES 揭示了另外 1 例 NOA 病例具有双等位基因 SHOC1 LoF 变异 (c.1464delT:p.D489Tfs*13)。据我们所知,这是第一份将 SHOC1 确定为人类 NOA 致病基因的报告。此外,我们的研究表明 NOA 中存在由 SHOC1 缺陷引起的常染色体隐性遗传模式。
The genetic causes of human idiopathic non-obstructive azoospermia (NOA) with meiotic arrest remain unclear. Two Chinese families with infertility participated in the study. In family 1, two brothers were affected by idiopathic NOA. In family 2, the proband was diagnosed with idiopathic NOA, and his elder sister suffered from infertility. Whole-exome sequencing (WES) was conducted in the two patients in family 1, the proband in family 2 and 362 additional sporadic patients with idiopathic NOA. Sanger sequencing was used to verify the WES results. Periodic acid–Schiff (PAS), immunohistochemistry (IHC) and meiotic chromosomal spread analyses were carried out to evaluate the stage of spermatogenesis arrested in the affected cases. We identified compound heterozygous loss of function (LoF) variants of SHOC1 (c.C1582T:p.R528X and c.231_232del:p.L78Sfs*9, respectively) in both affected cases with NOA from family 1. In family 2, homozygous LoF variant in SHOC1 (c.1194delA:p.L400Cfs*7) was identified in the siblings with infertility. PAS, IHC and meiotic chromosomal spread analyses demonstrated that the spermatogenesis was arrested at zygotene stage in the three patients with NOA. Consistent with the autosomal recessive mode of inheritance, all of these SHOC1 variants were inherited from heterozygous parental carriers. Intriguingly, WES of 362 sporadic NOA cases revealed one additional NOA case with a bi-allelic SHOC1 LoF variant (c.1464delT:p.D489Tfs*13). To the best of our knowledge, this is the first report identifying SHOC1 as the causative gene for human NOA. Furthermore, our study showed an autosomal recessive mode of inheritance in the NOA caused by SHOC1 deficiency.
