Because anencephaly is caused by abnormalities of the neural tube, it is classified as a neural tube defect. Because the neural tube fails to close properly, the developing brain and spinal cord are exposed to the amniotic fluid that surrounds the fetus in the womb.
Deficiency of the Alpha Chain of the IL-7 Receptor. Another form of SCID is due to mutations in a gene that encodes another growth factor receptor component, the alpha chain of the IL-7 receptor (IL-7RÎ±). When T, B and NK-cell counts are done, infants with this type have B-and NK-cells, but no T-cells. However, the B-cells do not work because of the lack of T-cells. IL-7RÎ± deficiency is the third most common cause of SCID accounting for 11% of SCID cases. It is inherited as an autosomal recessive trait. (See chapter titled âInheritance.â) Both boys and girls can be affected.
