Invitae RCV001972129 SCV002207528 uncertain significance Dilated cardiomyopathy 1G; Autosomal recessive limb-girdle muscular dystrophy type 2J 2024-01-18 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 35401 of the TTN protein (p.Glu35401Lys). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with TTN-related conditions. ClinVar contains an entry for this variant (Variation ID: 1435156). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. This variant is located in the M band of TTN (PMID: 25589632). Non-truncating variants in this region may be relevant for neuromuscular disorders, but have not been definitively shown to cause cardiomyopathy (PMID: 23975875). 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.
GenomeConnect - Invitae Patient Insights Network RCV003483863 SCV004228855 not provided Primary dilated cardiomyopathy; Autosomal recessive limb-girdle muscular dystrophy type 2J; Tibial muscular dystrophy no assertion provided phenotyping only Variant interpreted as Uncertain significance and reported on 02-03-2021 by Lab Invitae. GenomeConnect-Invitae Patient Insights Network assertions are reported exactly as they appear on the patient-provided report from the testing laboratory. Registry team members make no attempt to reinterpret the clinical significance of the variant. Phenotypic details are available under supporting information.
