Genes affected

OGFR (HGNC:15768): (opioid growth factor receptor) The protein encoded by this gene is a receptor for opioid growth factor (OGF), also known as [Met(5)]-enkephalin. OGF is a negative regulator of cell proliferation and tissue organization in a variety of processes. The encoded unbound receptor for OGF has been localized to the outer nuclear envelope, where it binds OGF and is translocated into the nucleus. The coding sequence of this gene contains a polymorphic region of 60 nt tandem imperfect repeat units. Several transcripts containing between zero and eight repeat units have been reported.

Collection Method:clinical testing

The c.560C>T (p.T187M) alteration is located in exon 6 (coding exon 6) of the OGFR gene. This alteration results from a C to T substitution at nucleotide position 560, causing the threonine (T) at amino acid position 187 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
