Cardiomyopathy, familial restrictive, 1

Restrictive cardiomyopathy (RCM) is a myocardial disease characterized by impaired ventricular filling and reduced diastolic volume in the presence of normal systolic function and normal or near-normal myocardial thickness. The disease is characterized by symptoms of progressive left- and right-sided heart failure. The overall prognosis is poor, especially when onset is in childhood, and patients often require cardiac transplantation (Mogensen et al., 2003). Genetic Heterogeneity of Familial Restrictive Cardiomyopathy Other forms of familial restrictive cardiomyopathy include RCM2 (609578), mapped to chromosome 10q23; RCM3 (612422), caused by mutation in the TNNT2 gene (191045) on chromosome 1q32; RCM4 (see 615248), caused by mutation in the MYPN gene (608517) on chromosome 10q21; RCM5 (see 617047), caused by mutation in the FLNC gene (102565) on chromosome 7q32; and RCM6 (619433), caused by mutation in the KIF20A gene (605664) on chromosome 5q31.
