Question

Immune deficiency disorder, which occurs due to mutation in a gene, involved in the maturation of T and B lymphocytes is ________.

• A. IDDM
• B. Hashimoto disease
• C. SCID
• D. Pernicious anemia

Answer 1

The correct option is C SCID

• Insulin-Dependent Diabetes Mellitus or IDDM is an immune deficiency disorder. It occurs due to a mutation in a gene involved in insulin-producing β cells in the pancreas.
• Hashimoto's disease is an autoimmune disorder that results in hypothyroidism. It results in defects in the maturation of T lymphocytes.
• Severe combined immunodeficiency (SCID) is an immunodeficiency syndrome. It occurs due to a mutation in the gene involved in the maturation of T and B lymphocytes.
• Pernicious anemia is also called as vitamin B${}_{12}$ deficiency syndrome. It results due to a lack of intrinsic factor.

Thus, the correct answer is 'Hashimoto disease and SCID.'
