Genes affected

NXPE3 (HGNC:28238): (neurexophilin and PC-esterase domain family member 3) This gene encodes a member of the neurexophilin family of neuropeptide-like glycoproteins. The encoded protein contains a variable N-terminal domain, a highly conserved neurexophilin and PC-esterase (NXPE) central domain, a short linker region, and a cysteine-rich C-terminal domain. This protein binds alpha neurexins, a group of presynaptic transmembrane receptors that promote adhesion between dendrites and axons. Alternative splicing results in multiple transcript variants.

The c.619A>G (p.R207G) alteration is located in exon 5 (coding exon 2) of the NXPE3 gene. This alteration results from a A to G substitution at nucleotide position 619, causing the arginine (R) at amino acid position 207 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
