Description

The p.L574V variant (also known as c.1720T>G), located in coding exon 11 of the NBN gene, results from a T to G substitution at nucleotide position 1720. The leucine at codon 574 is replaced by valine, an amino acid with highly similar properties. This amino acid position is well 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.
