Genes affected

NPEPPS (HGNC:7900): (aminopeptidase puromycin sensitive) This gene encodes the puromycin-sensitive aminopeptidase, a zinc metallopeptidase which hydrolyzes amino acids from the N-terminus of its substrate. The protein has been localized to both the cytoplasm and to cellular membranes. This enzyme degrades enkaphalins in the brain, and studies in mouse suggest that it is involved in proteolytic events regulating the cell cycle. [provided by RefSeq, Jul 2008]

Ambry Genetics

Feb 16, 2023

The c.2344G>A (p.V782I) alteration is located in exon 20 (coding exon 20) of the NPEPPS gene. This alteration results from a G to A substitution at nucleotide position 2344, causing the valine (V) at amino acid position 782 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
