Genes affected

PDYN (HGNC:8820): (prodynorphin) The protein encoded by this gene is a preproprotein that is proteolytically processed to form the secreted opioid peptides beta-neoendorphin, dynorphin, leu-enkephalin, rimorphin, and leumorphin. These peptides are ligands for the kappa-type of opioid receptor. Dynorphin is involved in modulating responses to several psychoactive substances, including cocaine. Multiple alternatively spliced transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2010]

PDYN-AS1 (HGNC:53462): (PDYN antisense RNA 1)

ACMG classification

Our verdict: Benign. The variant received -9 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.8).
• BP6: Variant 20-1979563-C-G is Benign according to our data. Variant chr20-1979563-C-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 898048.
• BS2: High AC in GnomAd4 at 53 AD gene.
