摘要: 青少年起病的成人型糖尿病(MODY)是一类以胰岛β细胞功能障碍为特征的、有较高遗传异质性的单基因遗传糖尿病。截至2022年8月,已发现14种明确的MODY致病基因。本文报道了1例疑似MODY患者,通过外显子组测序鉴定了1个胰岛素受体底物2(IRS2)基因突变,并在患者11名家系成员中进行了验证,提出IRS2基因是一个新的MODY候选致病基因,为MODY的诊断和治疗提供更多的参考资料。

Abstract:

Maturity-onset diabetes of the young (MODY) belongs to a kind of monogenic diabetes characterized by pancreatic β-cell dysfunction and high level of genetic heterogeneity. As of August 2022, 14 genes responsible for MODY have been identified clearly. In this paper, a case of suspected MODY was reported. A mutation in the insulin receptor substrate 2 (IRS2) gene was identified by exome sequencing, and also found in 11 family members of the patient. It is proposed that IRS2 gene may be a new candidate gene for MODY, informing the diagnosis and treatment of MODY.
