Genes affected

NINJ2 (HGNC:7825): (ninjurin 2) The protein encoded by this gene belongs to the ninjurin (for nerve injury induced) family. It is a cell surface adhesion protein that is upregulated in Schwann cells surrounding the distal segment of injured nerve, and promotes neurite outgrowth, thus may have a role in nerve regeneration after nerve injury.

The c.481A>G (p.T161A) alteration is located in exon 3 (coding exon 3) of the NINJ2 gene. This alteration results from a A to G substitution at nucleotide position 481, causing the threonine (T) at amino acid position 161 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
