Description

The c.5259+1G>A intronic variant results from a G to A substitution one nucleotide after coding exon 40 of the TSC2 gene. Alterations that disrupt the canonical splice site are expected to cause aberrant splicing. In silico splice site analysis predicts that this alteration will weaken the native splice donor site and will result in the creation or strengthening of a novel splice donor site. The resulting transcript is predicted to be in-frame and is not expected to trigger nonsense-mediated mRNA decay; however, direct evidence is unavailable. The exact functional effect of the altered amino acid sequence is unknown. This nucleotide position is highly conserved in available vertebrate species. Based on the available evidence, the clinical significance of this variant remains unclear.
