Genes affected

HCRTR1 (HGNC:4848): (hypocretin receptor 1) The protein encoded by this gene is a G-protein coupled receptor involved in the regulation of feeding behavior. The encoded protein selectively binds the hypothalamic neuropeptide orexin A. A related gene (HCRTR2) encodes a G-protein coupled receptor that binds orexin A and orexin B.

The c.584G>A (p.R195H) alteration is located in exon 5 (coding exon 3) of the HCRTR1 gene. This alteration results from a G to A substitution at nucleotide position 584, causing the arginine (R) at amino acid position 195 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
