Notes

rs768737101, also known as c.6988C>T, p.Arg2330Cys and R2330C, is a mutation in the DCHS1 gene on chromosome 11. Sequencing a family with several members affected by mitral valve prolapse (MVP) lead to the discovery of the rare rs768737101 mutation. Acting as an autosomal dominant, the rs768737101(A) allele was reported to be a causative mutation for MVP.
