Precocious puberty, simply put as
premature puberty, usually occurs in kids having a family history of precocious
findings will open the door for a new understanding of what controls the timing
of puberty," Dr Ursula Kaiser, co-senior
study author, explained. "It also will allow doctors to diagnose the cause of precocious
puberty in a subset of patients, or to identify patients at risk for developing
precocious puberty, especially if others in their family are affected."
whole-exome sequencing of 40 individuals from 15 different families, the
researchers identified mutation in the MKRN3 gene
, which caused production of
hormones associated with puberty.
young boys and girls hit their puberty at 15 and 12 respectively;
to precocious puberty, they may start displaying signs associated with puberty
as early as 9-10 years.
the finding of a genetic cause for central precocious puberty is a significant
contribution to further understanding human puberty, an explanation of why
puberty starts at about the time of the junction of the first and second
decades of human life has yet to be had," Professor Leuan Hughes,
Researchers also suggest that the
gene mutation may be just one factor affecting precocious puberty; several
other factors including environmental causes, chemical exposure
, and more,
could increase the risk of precocious puberty in kids considerably.
A cause of concern is that
precocious puberty is getting more and more common with the passage of time,
which further emphasizes the need for more such researches to be carried out.
