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]
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.

MAPT-AS1 (HGNC:43738): (MAPT antisense RNA 1) Implicated in Parkinson's disease. [provided by Alliance of Genome Resources, Apr 2022]

The c.442C>T (p.R148W) alteration is located in exon 6 (coding exon 6) of the CRHR1 gene. This alteration results from a C to T substitution at nucleotide position 442, causing the arginine (R) at amino acid position 148 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
