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

There isn't much in this article, but the closely related disorder, Delayed Sleep Phase Syndrome has a lot more information.

These are both bundled under the collective name of Circadian Rhythm Sleep Disorder, Which is certainly an interesting read.

Hope this is what you are looking for. :)
