Ambry Genetics RCV000575617 SCV000675401 uncertain significance Hereditary cancer-predisposing syndrome 2023-07-11 criteria provided, single submitter clinical testing The p.R768H variant (also known as c.2303G>A), located in coding exon 16 of the TSC1 gene, results from a G to A substitution at nucleotide position 2303. The arginine at codon 768 is replaced by histidine, an amino acid with highly similar properties. This amino acid position is 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.
