RCV001344050 | SCV001538079 | uncertain significance | Dilated cardiomyopathy 1G; Autosomal recessive limb-girdle muscular dystrophy type 2J | 2020-04-08 | criteria provided, single submitter | clinical testing | 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. Algorithms developed to predict the effect of missense changes on protein structure and function are unavailable for the TTN gene. 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). This variant has not been reported in the literature in individuals with TTN-related conditions. This variant is present in population databases (rs542891030, ExAC 0.02%). This sequence change replaces alanine with threonine at codon 34145 of the TTN protein (p.Ala34145Thr). There is a small physicochemical difference between alanine and threonine. |
