Final answer:

Severe Combined Immunodeficiency (SCID) is a genetic disorder that impairs the body's immune response and is caused by a mutation in B-cell and T-cell functions. It is primarily seen in males and is diagnosed in infancy. Bone marrow transplants are a common treatment for SCID.

Step-by-step explanation:

Severe Combined Immunodeficiency (SCID) is a genetic disorder that causes defects in both B-cell and T-cell functions, impairing the body's immune response to pathogens. SCID is primarily caused by an X-linked recessive mutation, and it affects males more commonly than females. Patients with SCID are typically diagnosed in infancy after developing severe opportunistic infections, and without treatment such as bone marrow transplants, they have a high risk of mortality.
