1. Cystic Fibrosis Inheritance Pattern
Autosomal Recessive
DescriptionAffects the lungs and digestive systemThe body produces very thick, sticky mucus
○clogs the lungs○blocks the pancreas & enzymes from
breaking down and absorbing food

Inheritance PatternAutosomal recessive
DescriptionAppear healthy at birthLack an enzyme – results in nervous
system damageUsually die by age 5More common in people of Jewish,
Irish, French-Canadian heritage
