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.

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.20405999).

The c.313T>C (p.S105P) alteration is located in exon 2 (coding exon 2) of the NINJ2 gene. This alteration results from a T to C substitution at nucleotide position 313, causing the serine (S) at amino acid position 105 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
