Description

The p.I26T variant (also known as c.77T>C), located in coding exon 2 of the PMS2 gene, results from a T to C substitution at nucleotide position 77. The isoleucine at codon 26 is replaced by threonine, 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.
