See (164761.0033) and Berndt et al. (1998).

In a patient with sporadic pheochromocytoma (171300), Neumann et al. (2002) identified the tyr791-to-phe (Y791F) substitution resulting from a 2372A-T transversion in exon 13 of the RET gene. The mutation was not identified in 600 control chromosomes.

Baumgartner-Parzer et al. (2005) found that in patients with familial medullary thyroid carcinoma, the Y791F mutation (which the authors referred to as PHE791TYR, F791Y) was associated with the nearby L769L SNP. All 12 individuals carrying Y791F (9 unrelated individuals and 3 descendants) were homozygous or heterozygous for the L769L polymorphism.

Frank-Raue et al. (2005) found this mutation coincident with a splice site mutation in MEN1 (131100.0034) in 3 members of a family with a multiple endocrine neoplasia phenotype. The RET Y791F mutation was carried in isolation by the father, who at 65 years of age had no thyroid or parathyroid disease and no pheochromocytoma, and no family history of medullary thyroid carcinoma, pheochromocytoma, or primary hyperparathyroidism. The authors concluded that the RET Y791F mutation and the MEN1 mutation did not interact.
