Description

The p.P28S variant (also known as c.82C>T), located in coding exon 1 of the MLH1 gene, results from a C to T substitution at nucleotide position 82. The proline at codon 28 is replaced by serine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
