Genes affected

GAP43 (HGNC:4140): (growth associated protein 43) The protein encoded by this gene has been termed a 'growth' or 'plasticity' protein because it is expressed at high levels in neuronal growth cones during development and axonal regeneration. This protein is considered a crucial component of an effective regenerative response in the nervous system. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

The c.713G>A (p.S238N) alteration is located in exon 3 (coding exon 2) of the GAP43 gene. This alteration results from a G to A substitution at nucleotide position 713, causing the serine (S) at amino acid position 238 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
