We demonstrate that missense mutations (Asp175Asn; Glu180Gly) in the alpha-tropomyosin gene cause familial hypertrophic cardiomyopathy (FHC) linked to chromosome 15q2. These findings implicated components of the troponin complex as candidate genes at other FHC loci, particularly cardiac troponin T, which was mapped in this study to chromosome 1q. Missense(More)
Noncompaction of the ventricular myocardium (NVM) is the morphological hallmark of a rare familial or sporadic unclassified heart disease of heterogeneous origin. NVM results presumably from a congenital developmental error and has been traced back to single point mutations in various genes. The objective of this study was to determine the underlying(More)
Highly purified nicking-closing enzyme from mouse cells in 20-fold enzyme/substrate excess converts closed circular native PM2, ColE1, and Minicol DNA into limit product sets of DNAs. Each set has a mean degree of supercoiling of approximately zero. The individual species in the sets differ by deltatau = +/-1, +/-2, etc., and the relative masses fit a(More)
A point mutation in exon 13 of the beta cardiac myosin heavy chain (MHC) gene is present in all individuals affected with familial hypertrophic cardiomyopathy (FHC) from a large kindred. This missense mutation converts a highly conserved arginine residue (Arg-403) to a glutamine. Affected individuals from an unrelated family lack this missense mutation, but(More)
An alpha/beta cardiac myosin heavy chain (MHC) hybrid gene is coinherited with familial hypertrophic cardiomyopathy (FHC) in one kindred. FHC is a disease of the heart muscle characterized by a thickening of the left ventricular wall with myocyte and myofibrillar disarray that is inherited as an autosomal dominant trait. We demonstrate here and in the(More)
DISSERTATION Genetic analysis in hypertrophic cardiomyopathy: missense mutations in the ventricular myosin regulatory light chain gene zur Erlangung des akademischen Grades Doctor medicinae (Dr. med.) Abstract Hypertrophic cardiomyopathy (HCM) is a heart disorder characterized by unexplained ventricular myocardial hypertrophy and a high risk of sudden(More)
Hypertrophic cardiomyopathy (HCM) is a dominant genetic disorder of the myocardium associated with dysfunctional contractile proteins. The major risk of HCM is sudden cardiac death, which may occur even in asymptomatic carriers. Causes are highly heterogeneous. Over 140 different mutations in nine sarcomeric genes have been described to date. The majority(More)
