Three pedigrees were identified in which mitral valve prolapse seemed to be inherited as a mendelian autosomal dominant trait. The segregation of the genes encoding the major fibrillar collagens present in valve tissue, collagens I and III, was analysed by use of restriction enzyme site variants as genetic markers. In one pedigree there was discordance between the segregation of the disease and markers for all three collagen genes. In another, there was discordance between the disease and markers for both collagen I loci. This is evidence against the disease being generally the result of mutations of the genes encoding the major fibrillar collagens.

Background: Mitral valve repair (MVr) is the gold standard treatment for degenerative mitral regurgitation, yet there is ongoing controversy regarding optimal anti-thrombotic therapy post-MVr. This scoping review aimed to summarise current evidence on the safety and efficacy of anti-thrombotic therapy after MVr, identify knowledge gaps and propose a future study design.
Methods: We searched MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Clinicaltrials.

Aims: Mitral valve prolapse (MVP) is a common valvular disorder associated with significant morbidity and mortality, with a strong genetic basis. This study aimed to identify a mutation in a family with MVP and to characterize the valve phenotype in LTBP2 knockout (KO) mice.
Methods And Results: Exome sequencing and segregation analysis were performed on a large family with MVP.
