Cystic Fibrosis

Cause of Cystic Frbrosis

Mutations in the CFTR gene cause cystic fibrosis. The CFTR gene provides instructions for making a channel that transports negatively charged particles called chloride ions into and out of cells.

How is it inherited?

The child receives one of his chromosome 7's from fathers sperm, and one from mothers egg. If both of these chromosomes have a mutated CFTR gene then the kid will have CF.

Will your next child have CF?

It is possible that your next child will not have CF. But if you have CF and your spouse is a carrier of CF then the chances are higher.
