20497437-2	2011	These mutations cause changes in either the cysteine-rich extracellular domain or, less commonly, the non-cysteine intracellular domains of the RET protein.	Cysteine	106-114	ret proto-oncogene	Homo sapiens	144-147	
20497437-3	2011	The genotype-phenotype correlations of classical cysteine RET mutations have been the subject of several comprehensive reviews.	Cysteine	49-57	ret proto-oncogene	Homo sapiens	58-61	
20497437-7	2011	This review summarizes the genotypic and phenotypic characteristics of RET codon 804 mutation, a prototype for the less well-defined non-cysteine RET mutations associated with MEN 2.	Cysteine	137-145	ret proto-oncogene	Homo sapiens	71-74
