|
a mutation affecting the Btk tyrosine kinase, halts B cell development at the pro- and pre-B cell in the bone marrow, with very few (usually <1%) B cells moving out of the bone marrow. Patients classically present in early infancy (ie, 4 to 6 months of age), when passive maternal antibody wanes and the B-cell defect prohibits mature B-cell and immunoglobulin production in the infant.
|
|
|
Severe combined immunodeficiency
defect? classic presentation? treatment? |
most often is due to a defect in the common gamma chain that is vital for intracellular signaling for interleukin (IL)-2, -4, -7, -9, -15, and -21 receptors. The defect impairs cellular function due to low concentrations of T lymphocytes and natural killer cells.
Patients typically present within the first 6 months after birth with failure to thrive, chronic diarrhea, and an eczematous rash that often is mistaken for atopic dermatitis. Immediate recognition and diagnosis is crucial because bone marrow transplantation prior to age 4 months of age is associated with improved survival. |

defect? presentation? treatment? |

Concentrations of IgM may be low, although IgG, IgA, B-cell, and T-cell concentrations are normal. WAS, an X-linked disease, is due to defects in the WAS protein that is a regulator in actin polymerization and hematopoietic cell development. Treatment includes stem cell transplantation, IVIG, management of bleeding diathesis, and antibiotics.

Children who have WS struggle with visuospatial relationships and understanding math concepts.
