NXPH2 (neurexophilin 2) is a signaling molecule that likely functions through binding to alpha-neurexins and possibly other receptors 1, acting as a neuropeptide-like factor in nervous system signaling pathways. The gene exhibits altered expression patterns in pancreatic ductal adenocarcinoma, where NXPH2 expression levels are significantly higher in tumor specimens compared to normal pancreatic tissue, potentially serving as a biomarker for tumor identification and lymph node metastasis assessment 2. Genetically, NXPH2 variants show associations with immune and disease susceptibility traits: a NXPH2 SNP (rs4954956) is associated with increased ovarian cancer risk, particularly serous histological subtypes 3, and separately, NXPH2 SNPs have demonstrated genome-wide significant association with HLA Class I alloimmunization in previously pregnant blood donors, suggesting a role in immune-mediated alloantibody formation 1. Recent genomic analyses identify NXPH2 as a novel gene associated with hemiplegic migraine 4 and reveal differential methylation patterns of NXPH2 in growth hormone-treated small-for-gestational-age newborns 5. These findings collectively suggest NXPH2 participates in immune regulation and may influence cancer development and neurological conditions, though molecular mechanisms remain incompletely understood.
