Description

The p.R640H variant (also known as c.1919G>A), located in coding exon 16 of the ACTN2 gene, results from a G to A substitution at nucleotide position 1919. The arginine at codon 640 is replaced by histidine, 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.
