Therefore, it has been classified as a Variant of Uncertain Significance. Loss-of-function variants in TSC2 are known to be pathogenic (PMID: 10205261, 17304050). However, exon 26 (sometimes referred to as exon 25 in the literature) has been shown to undergo alternative splicing and results in transcripts lacking exon 26 in many adult human tissues (PMID: 26703369). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site, but this prediction has not been confirmed by published transcriptional studies. This variant has not been reported in the literature in individuals with TSC2-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change affects a donor splice site in intron 26 of the TSC2 gene.
