概括

遗传性倾向于发生益生菌瘤是罕见的,主要影响患有巨型益生菌瘤的年轻患者. 在家族病例和30岁以下的个体中,MEN1和AIP的遗传检测至关重要.

科学领域:

  • 内分泌学 在内分泌学.
  • 遗传学 遗传学 是一个
  • 在瘤学瘤学.

背景情况:

  • 甲状腺瘤是常见的垂体瘤,但遗传性倾向的遗传基础在很大程度上仍未被探索.
  • 这项研究调查了与隔离性前性瘤患者的生殖线突变的流行情况,解决了重要的知识差距.

研究的目的:

  • 确定在被诊断患有隔离性益生菌瘤的大群患者中生殖线突变的患病率.
  • 为了确定与遗传性益生菌瘤相关的特定基因 (MEN1,AIP,CDKN1B,SF3B1).

主要方法:

  • 遗传和临床数据的回顾性分析来自506名患者的遗传测试 (2003-2020年).
  • 测试包括MEN1,AIP和CDKN1B基因,在突变阴性病例中对SF3B1进行桑格测序.

主要成果:

  • 在2.8%的患者 (14/506) 中发现了MEN1或AIP的生殖系突变 (可能的致病变异),仅在30岁之前诊断的巨细胞瘤患者中发现.
  • 在家族背景下 (15%) 的患病率更高,在30岁以下的零星病例中 (4%) 更高.
  • 在CDKN1B或SF3B1 (R625H) 中没有发现突变.

结论:

  • 与前乳腺瘤相关的生殖系突变主要在患有巨乳细胞瘤的年轻患者 (<30岁) 中被发现,特别是在家庭环境中.
关键词:
这是家族性腺瘤.遗传倾向 遗传倾向 遗传倾向遗传性垂体腺瘤 遗传性垂体腺瘤下垂体神经内分泌瘤患病率的流行情况.

  • 在30岁以上的患者中没有检测到任何致病变体,这表明年龄是关键因素.
  • 在患有前乳腺瘤的年轻患者中,特别是那些有家族病史的患者中,应考虑对MEN1和AIP进行遗传查.
