Women’s menstruation genes identified – Health News Article

Researchers from the Peninsula Medical School, along with collaborators from research institutions across Europe and the United States, have for the first time identified two genes that are involved in determining when girls begin menstruation.

The work will be published in Nature Genetics this weekend.

The findings of the study could have ramifications for normal human growth and weight too, because early-age menstruation is also associated with shorter stature and increased body weight. In general, girls who achieve menstruation earlier in life tend to have greater body mass index (BMI) and a higher ratio of fat compared to those who begin menstruation later.

The study carried out an analysis of 17,510 women across eight different international population-based sources. This number included women of European descent who reported the age at which they reached menstruation of between nine and 17 years.

The two genes identified were on chromosomes nine and six. One in 20 females carry two copies of each of the gene variations which result in menstruation starting earlier, and they will start menstruating approximately four an…
