Description

Reported in association with HCM (also reported as E138K using alternate nomenclature); at least two individuals were reported to also harbor variants in the MYH7 gene (Liu et al., 2013; Zou et al., 2013); Not observed at a significant frequency in large population cohorts (Lek et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; This variant is associated with the following publications: (PMID: 23283745, 23711808)
