In a discovery cohort of 770 index patients with HCM, 12 (1.56%) were heterozygous for ALPK3tv [odds ratio(OR) 16.11, 95% confidence interval (CI) 7.94-30.02, P = 8.05e-11] compared to the Genome Aggregation Database (gnomAD) population. In a validation cohort of 2047 HCM probands, 32 (1.56%) carried heterozygous ALPK3tv (OR 16.17, 95% CI 10.31-24.87, P Heterozygous ALPK3tv are pathogenic and segregate with a characteristic HCM phenotype.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/ALPK3GeneticsHypertrophic cardiomyopathyCardiomyopathy, HypertrophicHeterozygoteHumansMuscle ProteinsMutationProtein KinasesSarcomeresAlpha-protein kinase 3 (ALPK3) truncating variants are a cause of autosomal dominant hypertrophic cardiomyopathy.research article34263907open access10.1093/eurheartj/ehab4241522-9645PMC8380059https://academic.oup.com/eurheartj/article-pdf/42/32/3063/46627240/ehab424.pdfhttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC8380059/pdf
