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.

Collection Method: clinical testing

The c.46A>G (p.K16E) alteration is located in exon 1 (coding exon 1) of the NINJ2 gene. This alteration results from a A to G substitution at nucleotide position 46, causing the lysine (K) at amino acid position 16 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
