Cystic fibrosis

Cystic Fibrosis is a genetic disease.A child can only get Cystic Fibrosis if both of the child's parents are carriers of the disease.It is a recessive disease that requires both of the parents to carry the gene that causes Cystic Fibrosis
Cystic Fibrosis is recessive which is why most carriers have no clue that they are a carrier.In most cases the parents do not know that they are carriers, and show no signs of having the disease.
Usually we have 46 chromosomes, they pair up making 22 pairs, in each nucleus in our bodies.The left over two chromosomes are our sex chromosomes.Chromosome number 7 gets mutated and causes Cystic Fibrosis.
Cystic Fibrosis affects respiratory, digestive, and reproductive systems.There are many different symptoms, although they vary among each patient.
• Accumulation of thick mucus in the lungs and intestines
• Abnormal functioning of sweat and mucus producing glands
• clubbed fingers and toes (end of fingers and toes become inflated)
• enlargement of the right side of the heart
The average life span of a person suffering Cystic Fibrosis is 32 years, although there are some cases in which patients lived to be in their 50s and 60s.As of today there is no cure for the disease although there are treatments that help extend the life of a person living with Cystic Fibrosis.
There are about 67,000 people worldwide suffering from the illness.It most commonly affects Caucasians (1 in 25 are carriers) and Ashkenazi Jews (1 in 29 are carriers).Hispanics (1 in 49 are carriers), African Americans (1 in 65 are carriers), and Asians (1 in 150 are carriers) have a lesser risk of passing it on to their children and of being carriers.
