Description

The p.L60R variant (also known as c.179T>G), located in coding exon 1 of the CHEK2 gene, results from a T to G substitution at nucleotide position 179. The leucine at codon 60 is replaced by arginine, an amino acid with dissimilar 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.
