Description

The p.G231S variant (also known as c.691G>A), located in coding exon 3 of the PHOX2B gene, results from a G to A substitution at nucleotide position 691. The glycine at codon 231 is replaced by serine, an amino acid with similar properties. This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this alteration remains unclear.
