What is the most common fatal genetic disease in the US Huntington's disease color blindness hemophilia cystics fibrosis?
Cystic Fibrosis 1/3300 children affected
Duchenne Muscular Dystrophy 1/3600 boys affected
(Color blindness is not fatal, BTW)
What else can I help you with?
Is cystics fibrosis is caused by a mutation that is the dominant alle of a gene?
No, cystic fibrosis is an autosomal recessive disorder.
Is cystic fibrosis an infectious disease?
Good Question. The answer is cystic fibrosis is not contagious, however, people with cystic fibrosis tend to carry bacterial infections that can cause serious issues to other people with CF, so infection control procedures should be used when two or more cystics are around each other. General population folks need not fear of getting cystic fibrosis from others - it's a hereditary disease.
To be a cystic fibrosis carrier do your parents have to have a cystics fibrosis gene?
Yes, since the disease is a recessive inherted trait BOTH parents must carry the gene but will not have the disease itself. Approximately 30,000 people in the United States have cystic fibrosis. An additional ten million more-or about one in every 31 Americans-are carriers of the defective CF gene, but do not have the disease. The disease is most common in Caucasians, but it can affect all races.
The cause of sickle cell anemia is?
a child must inherit two copies of the defective gene in order to have a cystics fibrosis but when it come to sickle-cell anemia it is a disease passed down through families in which red blood cells from an abnormal sickle or crescent shape.Red blood cells carry oxygen to the body and are normally shaped like a disc so what causes sickle-cell anemia is the two copies that they get from both parents which gets passed down through families.
