Invitae RCV000545792 SCV000642587 uncertain significance Dilated cardiomyopathy 1G; Autosomal recessive limb-girdle muscular dystrophy type 2J 2017-07-09 criteria provided, single submitter clinical testing Algorithms developed to predict the effect of missense changes on protein structure and function are unavailable for the TTN gene. This variant identified in the TTN gene is located in the M band of the resulting protein (PMID: 25589632). It is unclear how this variant impacts the function of this protein. In summary, this variant is a novel missense change with unknown impact on protein function. Missense variants in this region of the TTN gene are typically not causative for cardiac disease, but may be relevant for neuromuscular disorders. However, the available evidence is currently insufficient to determine this variant’s role in disease. Therefore, it has been classified as a Variant of Uncertain Significance This variant has not been reported in the literature in individuals with TTN-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces valine with aspartic acid at codon 35358 of the TTN protein (p.Val35358Asp). There is a large physicochemical difference between valine and aspartic acid.
