Genes affected

NAPG (HGNC:7642): (NSF attachment protein gamma) This gene encodes soluble NSF attachment protein gamma. The soluble NSF attachment proteins (SNAPs) enable N-ethyl-maleimide-sensitive fusion protein (NSF) to bind to target membranes. NSF and SNAPs appear to be general components of the intracellular membrane fusion apparatus, and their action at specific sites of fusion must be controlled by SNAP receptors particular to the membranes being fused. The product of this gene mediates platelet exocytosis and controls the membrane fusion events of this process.[provided by RefSeq, Dec 2008]

The c.452G>A (p.R151Q) alteration is located in exon 8 (coding exon 8) of the NAPG gene. This alteration results from a G to A substitution at nucleotide position 452, causing the arginine (R) at amino acid position 151 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
