Fibrosis quística

The video discusses cystic fibrosis, a genetic disease caused by a mutation in a single gene on chromosome 7. This mutation leads to the production of a defective protein, causing thick mucus in the lungs and reducing life expectancy. The disease is inherited in a recessive manner, with a 25% chance of affecting a child if both parents are carriers. Despite identifying the gene in 1989, a cure remains elusive, though research continues to seek solutions.
