Description

The p.P268R variant (also known as c.803C>G), located in coding exon 3 of the IQSEC2 gene, results from a C to G substitution at nucleotide position 803. The proline at codon 268 is replaced by arginine, an amino acid with dissimilar properties. This amino acid position is not well 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.
