Correct Answer is C

Explanation

Explanation: The correct answer is c. X-linked agammaglobulinemia. This disorder primarily affects males and is caused by mutations in the BTK gene, resulting in a lack of mature B cells and immunoglobulins.

Incorrect choices:

a. Selective IgA deficiency is a primary immunodeficiency disorder characterized by a deficiency of immunoglobulin A (IgA), and it can affect both males and females.

b. DiGeorge syndrome is caused by a chromosome 22 deletion and is not inherited in an X-linked recessive pattern.

d. Severe combined immunodeficiency (SCID) is a group of disorders that can be inherited in various patterns, including autosomal recessive, autosomal dominant, or X-linked recessive. SCID affects both males and females and results in a severe deficiency of T cells, B cells, and natural killer (NK) cells.

A. Severe combined immunodeficiency (SCID) B. X-linked agammaglobulinemia (XLA) C. Wiskott-Aldrich syndrome D. Common variable immunodeficiency (CVID)

Correct Answer is A

Explanation

Explanation: The correct answer is a. Severe combined immunodeficiency (SCID). SCID is a severe and rare primary immunodeficiency disorder characterized by the absence or severe impairment of both T and B cells, leading to a profound deficiency in cellular and humoral immunity.

Incorrect choices:

b. X-linked agammaglobulinemia (XLA) primarily affects B-cell function, resulting in a lack of mature B cells and low levels of immunoglobulins, but does not typically involve T-cell deficiency.

c. Wiskott-Aldrich syndrome affects platelet function and immune system regulation, but it is not characterized by a deficiency of both T and B cells.

d. Common variable immunodeficiency (CVID) is characterized by reduced levels of immunoglobulins, particularly IgG and IgA, but it does not typically lead to a complete deficiency of both T and B cells.
