Description

This deletion of two nucleotides in MLH1 is denoted c.155_156delAA at the cDNA level and p.Lys52ArgfsX26 (K52RfsX26) at the protein level. The normal sequence, with the bases that are deleted in brackets, is GTTA[AA]GAGG. The deletion causes a frameshift, which changes a Lysine to an Arginine at codon 52, and creates a premature stop codon at position 26 of the new reading frame. Although this variant has not, to our knowledge, been reported in the literature, it is predicted to cause loss of normal protein function through either protein truncation or nonsense-mediated mRNA decay. we consider this variant to be pathogenic.
