Description

The Val15492Ile variant in TTN has not been reported in individuals with cardiom yopathy, but has been identified in 1/8270 European American chromosomes by the NHLBI Exome Sequencing Project and in 1/192 Kenyan chromosomes by the 1000 genom es project (http://evs.gs.washington.edu/EVS/; dbSNP rs190574498). Valine (Val) at position 15492 is generally conserved in evolution; however, the change to is oleucine (Ile) is present in one mammalian species (naked mole rat). Additional computational analyses (biochemical amino acid properties, AlignGVGD, PolyPhen2, and SIFT) do not provide strong support for or against an impact to the protein . Additional information is needed to fully assess the clinical significance of the Val15492Ile variant.
