*(HealthDay News via Yahoo News) — Researchers studying the link between diabetes and a hormone that affects your so-called “body clock” have identified a genetic mutation in the receptor for the hormone, melatonin, that may to boost the risk of the disease.
The finding could help improve assessment of a person’s diabetes risk and could also lead to the development of personalized treatments, according to the study published in the Jan. 29 online edition of the journal Nature Genetics.
The research team from Imperial College London found that people who have rare genetic mutations in the receptor for melatonin have a greatly increased risk for type 2 diabetes.
Melatonin controls the body’s sleep-wake cycle. A previous study found that people with common variations in the gene for the melatonin receptor MT2 have a slightly increased risk for type 2 diabetes.
This new study discovered that having any of four rare mutations of the MT2 is associated with a six times increased risk of developing type 2 diabetes.
