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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 20, 2023The c.173G>A (p.S58N) alteration is located in exon 5 (coding exon 2) of the NXPE3 gene. This alteration results from a G to A substitution at nucleotide position 173, causing the serine (S) at amino acid position 58 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
