p.Val371Met (GTG>ATG): c.1111 G>A in exon 12 of the CBS gene (NM_000071.2). The Val371Met mutation in the CBS gene has been reported in association with homocystinuria (Kluijtmans L et al., 1995). Kluijtmans et al. reported Val371Met in one individual with homocystinuria, who also harbored another mutation in the CBS gene. Val371Met results in a conservative amino acid substitution of one non-polar amino acid with another at a position that is conserved across species. Mutations in nearby residues (Cys370Tyr, Asp376Asn, Arg379Trp, Arg379Gln) have been reported in association with homocystinuria, further supporting the functional importance of this region of the protein. In summary, Val371Met in the CBS gene is interpreted as a disease-causing mutation. This variant was found in TAAD
