Abstract

Germline pathogenic variants (PVs) in CDH1 cause hereditary diffuse gastric cancer. The management of CDH1 cases with a positive family history includes total prophylactic gastrectomy or intensive surveillance. In this study, we report a 16-year-old boy with intramucosal gastric signet ring cells in the setting of a germline CDH1 PV and a family history of early-onset gastric cancer. The approach to managing both the proband and their 9-year-old sister, who also had the CDH1 PV, presented a challenge to both clinicians and the family. Herein, we present the complexities of managing gastric cancer risk when a CDH1 PV is identified in childhood in the setting of a family history of early-onset gastric cancer.

管理儿童 CDH1 癌症风险：遗传性弥漫性胃癌家庭的复杂决策。

CDH1 基因致病变体 (PV) 可导致遗传性弥漫性胃癌。对有阳性家族史的 CDH1 病例的治疗包括全胃切除术或强化监测。在本研究中，我们报告了一名患有粘膜内胃石样环细胞的 16 岁男孩，他的基因中含有 CDH1 PV，且家族中有早发胃癌病史。临床医生和患者家庭都面临着一个挑战，那就是如何同时治疗这名疑似患者及其同样患有 CDH1 PV 的 9 岁姐姐。在此，我们介绍了在有早发胃癌家族史的儿童期发现 CDH1 PV 时管理胃癌风险的复杂性。

期刊介绍： The American Journal of Medical Genetics - Part A (AJMG) gives you continuous coverage of all biological and medical aspects of genetic disorders and birth defects, as well as in-depth documentation of phenotype analysis within the current context of genotype/phenotype correlations. In addition to Part A , AJMG also publishes two other parts: Part B: Neuropsychiatric Genetics , covering experimental and clinical investigations of the genetic mechanisms underlying neurologic and psychiatric disorders. Part C: Seminars in Medical Genetics , guest-edited collections of thematic reviews of topical interest to the readership of AJMG .
