Hereditary cancer-predisposing syndrome Uncertain:1
The p.K997T variant (also known as c.2990A>C), located in coding exon 4 of the MSH6 gene, results from an A to C substitution at nucleotide position 2990. The lysine at codon 997 is replaced by threonine, an amino acid with similar properties. This amino acid position is 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.
