This documentary short explores the struggles of living with cystic fibrosis. Produced by and for Current TV.
Cystic fibrosis is a genetic disease of humans caused by homozygosity for a recessive gene (aa). In a particular large population, the frequency of newborns affected wth cystic fibrosis is 1 in 3,600. In this population, what proportion of marriages between genetically unrelated normal individuals is at risk of producing a child affected with cystic fibrosis? Is it:
1 family in 30
1 family in 300
1 family in 36
1 family in 900
1 family in 15
My friend had a little girl 2 weeks ago and today @ her 2 week check up she was told that the CF test they do in the hospital @ birth came back positive and they are re-testing and she will have results in 3 weeks. They also told her there is a high “false positive” rate.
Has anyone heard of this?
I am a CF carrier, and had to go to genetic counseling when my husband and I were in infertility treatment (he ended up not being a carrier) and never heard of this screen on infants…do they do it to them all? Are there false positives?? I just want to ease her mind.

-What specific part of the cell/structure allows the mucus secretions to be thick and viscous rather than fluid (i.e., is it a membrane channel, organelle or something else)? Please be specific and describe the step-by-step mechanism whereby this altered structure/part of the cell causes the secretions to contain less water.
-Why does Alvin have salt crystals forming on his skin? Explain the mechanism for this.
-What is the accepted treatment for children with cystic fibrosis? Make sure to list at least three and explain why they work (i.e., what is the purpose of each individual treatment).
-List and explain the mechanism of at least two experimental treatments that are currently being tried to help patients with cystic fibrosis.
-Briefly describe how gene therapy may help cure a genetically inherited disease like cystic fibrosis.

If you can’t answer all the questions (only some) that’s better than nothing.
