Genes affected

NPTXR (HGNC:7954): (neuronal pentraxin receptor) This gene encodes a protein similar to the rat neuronal pentraxin receptor. The rat pentraxin receptor is an integral membrane protein that is thought to mediate neuronal uptake of the snake venom toxin, taipoxin, and its transport into the synapses. Studies in rat indicate that translation of this mRNA initiates at a non-AUG (CUG) codon. This may also be true for mouse and human, based on strong sequence conservation amongst these species.

The c.1492G>A (p.A498T) alteration is located in exon 5 (coding exon 5) of the NPTXR gene. This alteration results from a G to A substitution at nucleotide position 1492, causing the alanine (A) at amino acid position 498 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
