Description

The p.T434K variant (also known as c.1301C>A), located in coding exon 13 of the MUTYH gene, results from a C to A substitution at nucleotide position 1301. The threonine at codon 434 is replaced by lysine, an amino acid with similar properties. This amino acid position is poorly 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.
