Description

The p.H618D variant (also known as c.1852C>G), located in coding exon 13 of the TSC1 gene, results from a C to G substitution at nucleotide position 1852. The histidine at codon 618 is replaced by aspartic acid, an amino acid with similar properties. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
