Description

The p.I885V variant (also known as c.2653A>G), located in coding exon 23 of the TSC2 gene, results from an A to G substitution at nucleotide position 2653. The isoleucine at codon 885 is replaced by valine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
