Invitae RCV001240470 SCV001413415 uncertain significance Dilated cardiomyopathy 1G; Autosomal recessive limb-girdle muscular dystrophy type 2J 2022-03-18 criteria provided, single submitter clinical testing This variant is located in the M band of TTN (PMID: 25589632). Variants in this region may be relevant for neuromuscular disorders, but have not been definitively shown to cause cardiomyopathy (PMID: 23975875). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. ClinVar contains an entry for this variant (Variation ID: 965916). This variant has not been reported in the literature in individuals affected with TTN-related conditions. This variant is present in population databases (rs368894429, gnomAD 0.007%). This sequence change replaces glycine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 33676 of the TTN protein (p.Gly33676Glu). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
