Description

The p.A137V variant (also known as c.410C>T), located in coding exon 5 of the MLH1 gene, results from a C to T substitution at nucleotide position 410. The alanine at codon 137 is replaced by valine, an amino acid with 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.
