Ambry Genetics RCV000561438 SCV000675698 uncertain significance Hereditary cancer-predisposing syndrome 2023-02-08 criteria provided, single submitter clinical testing The p.L1398V variant (also known as c.4192C>G), located in coding exon 33 of the TSC2 gene, results from a C to G substitution at nucleotide position 4192. The leucine at codon 1398 is replaced by valine, an amino acid with highly similar properties. This amino acid position is not well 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.
