Dilated Cardiomyopathy and conduction defects
Gene: MYH7Comment on mode of inheritance: Association with monoallelic variants is well-established. To date, only four families have been reported with recessive variants (PMIDs: 14659406; 25666907; 17372140; 31130376). Of these, one family developed dilated cardiomyopathy and one had hypertrophic cardiomyopathy, while cardiac function was normal in the remaining two families. Therefore, maintaining MOI of monoallelic only at this time but with a watchlist_moi tag to monitor for evidence linking biallelic variants linked to DCM.Created: 10 Oct 2022, 1:16 p.m. | Last Modified: 10 Oct 2022, 1:19 p.m.
