There is a name to a sleeping disorder that is inherited through the maternal line.

Passing from mother to daughter. The sleep cyle is from 7pm to 2 am. It was featured

approx. 12 years ago on TV. It showed this particular family living normal lives.

I am trying to find the name to this disorder to assist my physician.

Can you help.

Sounds like Familial Advanced Sleep Phase Syndrome (http://en.wikipedia.org/wiki/Advanced_sleep_phase_syndrome)

There isn't much in this article, but the closely related disorder, Delayed Sleep Phase Syndrome (http://en.wikipedia.org/wiki/Delayed_sleep_phase_syndrome) has a lot more information.

These are both bundled under the collective name of Circadian Rhythm Sleep Disorder (http://en.wikipedia.org/wiki/Circadian_rhythm_sleep_disorder), Which is certainly an interesting read.

Hope this is what you are looking for. :)
