Genes affected
MTNR1B (HGNC:7464): (melatonin receptor 1B) This gene encodes one of two high affinity forms of a receptor for melatonin, the primary hormone secreted by the pineal gland. This gene product is an integral membrane protein that is a G-protein coupled, 7-transmembrane receptor. It is found primarily in the retina and brain although this detection requires RT-PCR. It is thought to participate in light-dependent functions in the retina and may be involved in the neurobiological effects of melatonin. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 28, 2024The c.352T>C (p.F118L) alteration is located in exon 2 (coding exon 2) of the MTNR1B gene. This alteration results from a T to C substitution at nucleotide position 352, causing the phenylalanine (F) at amino acid position 118 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
