Abstract

We have constructed a high-resolution genetic linkage map in the vicinity of the gene responsible for multiple endocrine neoplasia type 1 (MEN1). The mutation causing this disease, inherited as an autosomal dominant, predisposes carriers to development of neoplastic tumors in the parathyroid, the endocrine pancreas, and the anterior lobe of the pituitary. The 12 markers on the genetic linkage map reported here span nearly 20 cM, and linkage analysis of MEN1 pedigrees has placed the MEN1 locus within the 8-cM region between D11S480 and D11S546. The markers on this map will be useful for prenatal or presymptomatic diagnosis of individuals in families that segregate a mutant allele of the MEN1 gene.

摘要

我们构建了一个与1型多发性内分泌腺瘤(MEN1)相关基因附近的高分辨率遗传连锁图谱。导致这种疾病的突变以常染色体显性方式遗传,使携带者易患甲状旁腺、内分泌胰腺和垂体前叶的肿瘤。本文报道的遗传连锁图谱上的12个标记跨度近20厘摩,对MEN1家系的连锁分析已将MEN1基因座定位于D11S480和D11S546之间8厘摩的区域内。该图谱上的标记将有助于对携带MEN1基因突变等位基因的家系中的个体进行产前或症状前诊断。
