傅嫈惠说，她的团队已经发现了更多与睡眠时间短有关的基因突变。

Fu say her team has already discovered more sleep-shortening mutations .

加州大学旧金山分校的傅嫈惠和她的同事们一直在寻找和研究那些所需睡眠少于平均水平的家庭。

Ying-Hui Fu at the University of California , San Francisco , and her colleagues have been seeking out and studying families in which some people seem to need less sleep than normal .

今年8月，傅嫈惠的研究小组报告称，ADRB1基因突变使一个家庭的12名成员每晚只睡4.5小时而不会感到疲劳。

In August , Fu 's team reported that a mutation in a gene called ADRB1 allows 12 members of a family to sleep as little as 4.5 hours per night without feeling tired .

然而，就傅嫈惠的研究小组所知，那些因为拥有这些基因变异而睡眠较少的人是健康的，而且似乎没有任何不良影响。

As far as Fu 's team has been able to tell , however , people who sleep less because they have one of these gene variants are healthy and don 't appear to suffer any ill effects .
