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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 15, 2023The c.686G>T (p.R229L) alteration is located in exon 2 (coding exon 2) of the PENK gene. This alteration results from a G to T substitution at nucleotide position 686, causing the arginine (R) at amino acid position 229 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
