MEN2A and MEN2B have recently been mapped within the centromeric region closely linked to RBP3 and D10S15 (which are located inside the deletion) and cosegregate with HSCR in at least two different pedigrees.

This information is relevant for the screening of recently reported missense mutations of RET which cause Multiple Endocrine Neoplasia 2A (MEN2A) and for the search of additional point mutations of the same gene which might cause two other neural crest disorders, MEN2B and Hirschsprung disease, mapping in the same region as MEN2A.

Using flanking intronic sequences as primers to amplify 12 of the 20 exons of RET from genomic DNA of 27 Hirschsprung's disease patients, we have now identified four mutations (one frameshift and three missense) that totally disrupt or partially change the structure of the tyrosine kinase domain of the RET protein (Ret).

We have examined the following possible linked markers in 69 relatives in this family: the c-ret gene (HSCR); the human PAX3 gene (HuP2) on chromosome 2q (WS1) and placental alkaline phosphatase (ALPP) on chromosome 2q (linked to WS1); argininosuccinate synthetase (ASS) on chromosome 9q, close to ABO blood groups which have shown weak linkage to WS; and the beta 1 GABA receptor gene (GABARB1) on chromosome 4q13-11, close to c-kit, deletions of which cause piebaldism.

Taken together, the low penetrance of the mutant gene, the lack of genotype-phenotype correlation, the sex-dependent effect of RET mutations and the variable clinical expression of the disease support the existence of one or more modifier genes in familial HSCR.

RET is a receptor tyrosine kinase gene which is responsible for three different inherited cancer syndromes namely multiple endocrine neoplasia type 2A (MEN 2A), type 2B (MEN 2B) and familial medullary thyroid carcinoma (FMTC) as well as for Hirschsprung disease (HSCR), a congenital disorder affecting the intestinal motility.
