What else can I help you with?
How would a child inherit PKU?
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.
What causes Pick disease?
The molecular cause of Pick disease are a series of mutations linked to chromosomes 17, 9 and 3
A defect in the enzyme which converts phenylalanine into tyrosine is characteristic of what disease?
PKU
Is pku disease an autosomal dominant trait?
It is an autosomal recessive trait.
Is PKU fatal?
no, you can get a mental disease but you cannot die from it exactly
What amino acid component of aspartame or nutarsweet causes PKU?
phenylalanine
Is pku sex linked recessive or sex dominant?
I think I read somewhere that there are some variants of it that are recessive and others that are dominant.
Is there anything bad in phenylalanine?
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.
Why is it that two normal parents could have a child with 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.
What does PKU stand for?
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.
How are the cause and onset of symptoms of huntingtons disease different from of PKU and Tay-Sachs disease?
Typcially, onset of symptoms with HD is from the mid 30-s to 40's.
Is huntingtons disease due to lack of chromosomes?
No, the Huntington's disease is inherited from either the mother or father. It's genes not a lack of chromosomes.
