Description

The p.L1449F variant (also known as c.4347A>C), located in coding exon 28 of the ATM gene, results from an A to C substitution at nucleotide position 4347. The leucine at codon 1449 is replaced by phenylalanine, 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.
