Cystic fibrosis affected by genetic variations
The severity of cystic fibrosis, a hereditary condition that affects the lungs and digestive system and results in an average life span of only 30 years, is affected by genetic variations according to recent research.
Researchers at Harvard Medical School and Children's Hospital Boston have retraced the evolution of an unusual bacterial infection as it spread among cystic fibrosis patients by sequencing scores of samples collected during the outbreak, since contained.
