Abstract

The RET and the Pax 3 genes have recently been shown to account for autosomal dominant Hirschsprung's disease (HSCR) and Waardenburg syndrome type 1 (WS1) respectively, which led us to consider them as candidate genes in the WS/HSCR association. Linkage analyses performed in a consanguineous WS/HSCR family support the view that neither the RET locus nor the Pax 3 locus are involved in the disease phenotype. Hence, at least one further locus altering neural crest cell development is responsible for the pleiotropic features observed in the WS/HSCR association.

摘要

RET基因和Pax 3基因最近分别被证明与常染色体显性遗传的先天性巨结肠症(HSCR)和1型瓦登伯革氏综合征(WS1)有关,这使我们将它们视为WS/HSCR关联中的候选基因。在一个近亲结婚的WS/HSCR家族中进行的连锁分析支持这样一种观点,即RET基因座和Pax 3基因座均不参与该疾病的表型。因此,至少还有一个改变神经嵴细胞发育的基因座导致了WS/HSCR关联中观察到的多效性特征。
