Genes affected

OPRD1 (HGNC:8153): (opioid receptor delta 1) Enables G protein-coupled enkephalin receptor activity. Involved in several processes, including G protein-coupled opioid receptor signaling pathway; cellular response to hypoxia; and positive regulation of peptidyl-serine phosphorylation. Is intrinsic component of plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.413C>T (p.T138M) alteration is located in exon 2 (coding exon 2) of the OPRD1 gene. This alteration results from a C to T substitution at nucleotide position 413, causing the threonine (T) at amino acid position 138 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
