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]

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces arginine, which is basic and polar, with serine, which is neutral and polar, at codon 138 of the PDYN protein (p.Arg138Ser). This variant is present in population databases (rs267606941, gnomAD 0.01%). This missense change has been observed in individual(s) with clinical features of spinocerebellar ataxia (PMID: 21035104, 22287014, 23355175). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 18458). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt PDYN protein function with a negative predictive value of 80%. Studies have shown that this missense change alters PDYN gene expression (PMID: 21035104). For these reasons, this variant has been classified as Pathogenic. -
