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 GeneticsJun 13, 2024The c.359G>A (p.G120D) 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 359, causing the glycine (G) at amino acid position 120 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
