Genes affected

LINC02210-CRHR1 (HGNC:51483): (LINC02210-CRHR1 readthrough) This locus represents naturally occurring readthrough transcription between neighboring genes CRHR1-IT1, CRHR1 intronic transcript 1 (Gene ID: 147081) and CRHR1, corticotropin releasing hormone receptor 1 (Gene ID: 1394) on chromosome 17. The readthrough transcript encodes a protein that shares sequence identity with the product of the CRHR1 gene. [provided by RefSeq, Dec 2016]

LINC02210-CRHR1 links:

CRHR1 (HGNC:2357): (corticotropin releasing hormone receptor 1) This gene encodes a G-protein coupled receptor that binds neuropeptides of the corticotropin releasing hormone family that are major regulators of the hypothalamic-pituitary-adrenal pathway. The encoded protein is essential for the activation of signal transduction pathways that regulate diverse physiological processes including stress, reproduction, immune response and obesity. Alternative splicing results in multiple transcript variants. Naturally-occurring readthrough transcription between this gene and upstream GeneID:147081 results in transcripts that encode isoforms that share similarity with the products of this gene.

Collection Method:clinical testing

The c.169C>T (p.R57C) alteration is located in exon 3 (coding exon 3) of the CRHR1 gene. This alteration results from a C to T substitution at nucleotide position 169, causing the arginine (R) at amino acid position 57 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
