| Invitae | RCV001059537 | SCV001224164 | uncertain significance | Dilated cardiomyopathy 1G; Autosomal recessive limb-girdle muscular dystrophy type 2J | 2020-02-15 | 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 sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. 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 A band of TTN (PMID: 25589632). Variants in this region may be relevant for cardiac or neuromuscular disorders (PMID: 25589632, 23975875). This variant has been observed in individual(s) with clinical features of autosomal recessive limb-girdle muscular dystrophy (Invitae). This variant is not present in population databases (ExAC no frequency). This sequence change replaces alanine with glycine at codon 33066 of the TTN protein (p.Ala33066Gly). There is a small physicochemical difference between alanine and glycine. |
