Description

The p.Q558K variant (also known as c.1672C>A), located in coding exon 18 of the STXBP1 gene, results from a C to A substitution at nucleotide position 1672. The glutamine at codon 558 is replaced by lysine, an amino acid with 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.
