Description

The p.L890V variant (also known as c.2668C>G), located in coding exon 17 of the ATM gene, results from a C to G substitution at nucleotide position 2668. The leucine at codon 890 is replaced by valine, an amino acid with highly similar properties. This amino acid position is highly 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.
