Chinese scientists have found that freckles, a nuisance for many people, are
caused by certain genetic variations.
Freckles have long
been a nuisance for beauty-seeking girls. [file

that accidental genetic changes in chromosome No. 4 caused freckles in several
generations of a Chinese family, says Prof. Zhang Xuejun, a skin disease
specialist with the Anhui Medical Sciences University in the eastern Anhui
Province.
Prof. Zhang and his colleagues used state-of-the-art genome scanning
technologies to analyze the samples before they came to the conclusion.
"We have to rely on genetic technologies to remove freckles, because present
freckle removal solutions with laser technologies or medicine will not have
long-lasting effects," said Prof. Zhang.
He said they were among the first in the world to localize the freckle gene,
and the finding marked a milestone in China's research on skin diseases caused
by abnormal pigmentation.
The finding had been summarized into a thesis, which was published recently
in a leading international dermatology magazine, said Prof.
Zhang.
