12 th chromosome
A child inherits PKU if both parents are carriers of the gene mutation that causes the condition. When both parents are carriers, there is a 25% chance with each pregnancy that the child will inherit two copies of the mutated gene and have PKU.
The molecular cause of Pick disease are a series of mutations linked to chromosomes 17, 9 and 3
PKU
It is an autosomal recessive trait.
no, you can get a mental disease but you cannot die from it exactly
phenylalanine
I think I read somewhere that there are some variants of it that are recessive and others that are dominant.
No, it is simply put on packages and soda cans because there is a specific disease that can harm people if they ingest it. The disease is phenylketonuria, or PKU. It is a genetic disorder that keeps your body from metabolizing phenylalanine, which is an amino acid. If you have PKU and eat too much phenylalanine, it will cause mental retardation. NutraSweet has phenylalanine in it, so they don't want PKU sufferers to use it for obvious reasons. So...phenylalanine is okay for you if you don't have PKU.
PKU, phenolketonuria, is a genetic disease caused by a recessive gene. So, a person with one normal and one faulty gene for this characteristic will not have the disease, you have to have two faulty genes to have the disease. If two people who each have one gene for PKU have a child, that child can inherit the gene from each parent and therefore will have two copies, causing the recessive trait to manifest.
Phenylketonuria (PKU) is not an eating disorder. It is an inherited disorder which the body cannot break down phenylalanine, which is a part of protein. If PKU is not treated soon after birth, it can cause brain and nervous system damage.
Typcially, onset of symptoms with HD is from the mid 30-s to 40's.
No, the Huntington's disease is inherited from either the mother or father. It's genes not a lack of chromosomes.
