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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 21, 2022The c.514G>A (p.G172S) 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 514, causing the glycine (G) at amino acid position 172 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
