So the disease that i want to talk about today is huntington's disease.
00:04
And huntington's is a really kind of intense disorder which is caused by a disorder that affects the brain and the nervous system.
00:19
And huntington's disease will result in the nerve degradation in the brain causing a lot of cognitive issues.
00:30
And it's not, it's very rare so it's not super common, but we do know it's an inheritance pattern.
00:39
So it is autosomal dominant.
00:41
So what that means is that you only need one gene to be affected.
00:49
So if it's autosomal dominant, let's say that, and we can draw our punnett square so we can kind of discuss the underlying inheritance pattern.
01:01
So one parent has huntington's and the other parent doesn't.
01:17
Because it's autosomal dominant, anyone with the gene is infected.
01:22
So there isn't a carrier situation here which you have with autosomal recessive or recessive inheritance.
01:31
So 50 % of the offspring have, there's a 50 % chance that the offspring have huntington's as if one of the parents has it.
01:42
If both of the parents have it, there's a 75 % chance of it because you would have hh, or 100 % rather...
