Genetic Variant HCRTR1:p.Arg162Cys (chr1-31620948-C-T) – ACMG Classification: Likely_benign (-1 pts)

Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 0P and 1B. BP4

The NM_001525.3(HCRTR1):c.484C>T(p.Arg162Cys) variant causes a missense change. The variant allele was found at a frequency of 0.000044 in 1,614,058 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R162H) has been classified as Uncertain significance.

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.
