Cambridge scientists identify six genes which they say 'profoundly' affect the timing of puberty.
Cambridge University researchers studied the DNA of around 800,000 women from Europe, North America, China, Japan, and Korearesearchers studied the DNA of around 800,000 women from Europe, North America, China, Japan, and Korea., on Monday.
Dr Kentistou, lead study investigator, added: “This is the first time we’ve ever been able to analyse rare genetic variants at this scale."While these genes were discovered in girls, they often have the same impact on the timing of puberty in boys."Scientists involved in the study said there was a link between early puberty and weight gain.
"This can then lead to potentially serious health problems in later life, as having earlier puberty leads to higher rates of overweight and obesity in adulthood.”The university said, in its statement, that the age at which girls hit puberty and started having periods normally occurred between 10 to 15."The reasons for this are not fully understood.
