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.

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.47G>T (p.G16V) alteration is located in exon 3 (coding exon 1) of the HCRTR1 gene. This alteration results from a G to T substitution at nucleotide position 47, causing the glycine (G) at amino acid position 16 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
