Labcorp Genetics (formerly Invitae), Labcorp RCV003510358 SCV004333518 uncertain significance Primary dilated cardiomyopathy 2023-04-09 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 disrupt the consensus splice site. This variant has not been reported in the literature in individuals affected with TXNRD2-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.003%). This sequence change affects an acceptor splice site in intron 3 of the TXNRD2 gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), however the current clinical and genetic evidence is not sufficient to establish whether loss-of-function variants in TXNRD2 cause disease.
