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.

NINJ2-AS1 (HGNC:40405): (NINJ2 antisense RNA 1)

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.8).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.177 is higher than 0.05.
