The inheritance pattern described in the scenario is best characterized as pleiotropy. This is because a single gene mutation affects multiple systems (immune system, lungs, heart, and kidneys) in the affected individuals. Pleiotropy refers to the phenomenon where one gene influences multiple phenotypic traits.
A genetic disease is found in a family that affects the immune system, lungs, heart, and kidneys. A DNA analysis of several affected and unaffected family members determines that the disease is caused by a mutation in a single gene.
