Question

A relatively rare genetic condition in which a child is born without functional B cells or T cells is SCID, or severe_________ immunodeficiency

1. Combined
2. Congenital
3. Chronic
4. Cellular

Answer 1

Severe Combined Immunodeficiency (SCID) is a rare genetic condition where a child is born without functional B cells or T cells. The correct term for SCID is 'Combined', thus the answer is 1. 'Combined'.

Step-by-step explanation:

A relatively rare genetic condition in which a child is born without functional B cells or T cells is called Severe Combined Immunodeficiency (SCID), also known as “bubble boy disease.” Patients with this condition have defective B-cell and T-cell production, which impairs T-cell dependent antibody responses as well as cell-mediated immune responses. Because of these defects, patients with SCID lack adaptive immunity, making them extremely susceptible to infections, and cannot develop immunological memory, leading to the inability for vaccines to provide protection. The correct term to fill in the blank for the acronym SCID is 'Combined', making the answer to the question number 1. 'Combined'.
