Invitae RCV000467160 SCV000542498 uncertain significance Dilated cardiomyopathy 1G; Autosomal recessive limb-girdle muscular dystrophy type 2J 2016-10-26 criteria provided, single submitter clinical testing This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a TTN-related disease. In summary, this is a novel silent change with uncertain impact on splicing. In addition, it is not located in a clinically relevant region of the TTN gene (PMID: 25589632). For these reasons it has been classified as a Variant of Uncertain Significance. Nucleotide substitutions within the consensus splice site are relatively common causes of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of nucleotide changes on RNA splicing suggest that this variant may alter RNA splicing, but this prediction has not been confirmed by published transcriptional studies. This sequence change falls in intron 125 of the TTN gene. It does not directly change the encoded amino acid sequence of the TTN protein.
