Description

The p.I882V variant (also known as c.2644A>G), located in coding exon 17 of the ATM gene, results from an A to G substitution at nucleotide position 2644. The isoleucine at codon 882 is replaced by valine, an amino acid with highly similar properties. This alteration has been reported in normal population control subjects (Tiao G et al. Leukemia, 2017 Oct;31:2244-2247). This amino acid position is poorly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
