Description

The Pro90Leu variant has been reported in one individual with HCM and was absent from 400 control chromosomes (200 White, 200 Black; Bos 2006). Of note, this i ndividual also carried a MYBPC3 variant of possible significance (Gln998Arg). O ur laboratory has detected the Pro90Leu variant in 1 Caucasian DCM proband (out of >336 Caucasian probands tested). Proline (Pro) at position 90 is conserved a cross evolutionary distant species, suggesting that a change would not be tolera ted. However it is not conserved in a single mammalian species (chimp has an al anine), making it difficult to interpret this data. Three computer tools (Polyp hen2, SIFT, MAPP) predict this change to be deleterious; however, their accuracy is unknown. In summary, additional data (functional/segregation/control studies ) is needed to determine the clinical significance of this variant.
