Description

The p.M1026V variant (also known as c.3076A>G), located in coding exon 15 of the BLM gene, results from an A to G substitution at nucleotide position 3076. The methionine at codon 1026 is replaced by valine, an amino acid with highly similar properties. This amino acid position is conserved. 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.
