Since cystic fibrosis is a genetic recessive disease, it may also be presyptomatic or asymptomatic in the family members of people with the condition. Once a diagnosis has been made, screening for family members (particularly siblings) is worth considering. Even in those who are pre/asymptomatic, knowing the mutation exists could give a much-needed head-start on treatment, allow for detection of carriers, and enable loved ones to make informed choices when planning for the future.[1]
Does the genetic cause of cystic fibrosis have any other impact?

Cystic fibrosis, because it is a genetic recessive disease, can be presymptomatic or asymptomatic in family members, which makes screening advisable for siblings. Identifying the mutation can facilitate early treatment, carrier detection, and informed decision-making for families.
