SCID has deficiencies in what cells?
B AND T cells
The Autosomal Recessive version of SCID lacks what and has a buildup of what?
Lacks Adenosine deaminase
Has a buildup of toxic purines
The Autosomal Recessive version of SCID lacks Adenosine Deaminase. What does that block?
T cell formation
If T cell formation is blocked, what will that suppress?
B cell function
The X-linked version of SCID has mutations in?
IL receptors
The X-linked version of SCID has mutations in IL receptors. What does this decrease?
T and B cells
SCID has deficiencies in what cells?
B AND T cells
DiGeorge Syndrome has a deletion of?
22q11
Deletion of 22q11
DiGeorge Syndrome
What cell is specifically impacted in DiGeorge Syndrome?
T cells due to lack of thymus
What pharyngeal pouches are missing/partial with DiGeorge syndrome?
3 and 4
- No thymus, No parathyroid, great vessel/heart abnormalities
Symptoms of DiGeorge Syndrome?
T cell deficiency that could impact B cells function
- Facial/cardiac anomalies, hypocalcemia (tetany)
Symptoms of DiGeorge Syndrome?
T cell deficiency that could impact B cells function

What gene on what chromosome is affected by X-linked Agammaglobulinemia?
BTK gene on X chromosome
Bruton Tyrosine Kinase
Defect in BTK gene
X-linked Agammaglobulinemia
What cells are affected and how with X-linked Agammaglobulinemia?
Pre-B cells can’t mature
Those with X-linked Agammaglobulinemia’s risk for infection increases as?
