Bone complications due to cystic fibrosis have a genetic cause, according to an MUHC study

A recent MUHC study reveals that cystic fibrosis-related bone problems are an additional pathology stemming from the Cftr gene mutation, not a side effect of treatment. The study found that mice with the mutation have lower bone mineral density and mass than control mice, without pancreatic insufficiency or steroid treatment.
