Germ-line mutations of the RET proto-oncogene in multiple endocrine neoplasia type 2A
This work has identified missense mutations of the RET proto-oncogene in 20 of 23 apparently distinct MEN 2A families, but not in 23 normal controls, and found that 19 of these 20 mutations affect the same conserved cysteine residue at the boundary of theRET extracellular and transmembrane domains.
The relationship between specific RET proto-oncogene mutations and disease phenotype in multiple endocrine neoplasia type 2. International RET mutation consortium analysis.
It is suggested that genotype-phenotype correlations do exist and, if made reliably absolute, could prove useful in the future in clinical management with respect to screening, surveillance, and prophylaxis, as well as provide insight into the genetic effects of particular mutations.
Specific mutations of the RET proto-oncogene are related to disease phenotype in MEN 2A and FMTC
The data show a strong correlation between disease phenotype and the nature and position of theRET mutation, suggesting that a simple, constitutive activation of the RET tyrosine kinase is unlikely to explain the events leading to MEN 2A and FMTC.

The complex roles of RET in homeostasis and survival of neural lineages and in tumour-associated inflammation might also suggest potential long-term pitfalls of broadly targeting RET.
Point mutation within the tyrosine kinase domain of the RET proto-oncogene in multiple endocrine neoplasia type 2B and related sporadic tumours.
A missense mutation, resulting in the substitution of a threonine for a methionine at codon 918 in the tyrosine kinase catalytic domain, is reported in the germline of 26 of 28 apparently distinct families with MEN 2B.
Genotype‐phenotype correlation in multiple endocrine neoplasia type 2: report of the International RET Mutation Consortium
Abstract. The International RET Mutation Consortium was first convened as part of the Fifth International Workshop on Multiple Endocrine Neoplasia, Stockholm, Sweden, in an attempt to analyse the…
Mutations of the RET proto-oncogene in Hirschsprung's disease
No recombination was observed between the disease locus and the locus for the RET proto-oncogene, a protein tyrosine kinase gene expressed in the cells derived from the neural crest, and it is shown that the mutant genotypes segregate with the disease in HSCR families.
Mutations of the RET proto‐oncogene in the multiple endocrine neoplasia type 2 syndromes, related sporadic tumours, and Hirschsprung disease
Mutations in the RET proto‐oncogene have been found in patients with the multiple endocrine neoplasia type 2 syndromes, the related sporadic tumours medullary thyroid carcinoma and pheochromocytoma, and familial and sporadic Hirschsprung disease, a syndrome of congenital absence of enteric innervation.
Diversity of RET proto-oncogene mutations in familial and sporadic Hirschsprung disease.
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.
