Genes affected

PENK (HGNC:8831): (proenkephalin) This gene encodes a preproprotein that is proteolytically processed to generate multiple protein products. These products include the pentapeptide opioids Met-enkephalin and Leu-enkephalin, which are stored in synaptic vesicles, then released into the synapse where they bind to mu- and delta-opioid receptors to modulate the perception of pain. Other non-opioid cleavage products may function in distinct biological activities. [provided by RefSeq, Jul 2015]

Ambry Genetics

Mar 15, 2024

The c.68G>T (p.R23L) alteration is located in exon 1 (coding exon 1) of the PENK gene. This alteration results from a G to T substitution at nucleotide position 68, causing the arginine (R) at amino acid position 23 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
