Abstract

Ataxia telangiectasia (AT) is a rare multisystem, neurodegenerative genetic disorder. Due to its wide clinical heterogeneity, it often leads physicians to an incorrect or missed diagnosis, and insight into this rare disease is important. Here is a case report of two cousins from the same family who showed salient characteristic features of AT along with the incidental finding of co-inheritance of hemoglobin E trait. Though both of them were from the same family, they showed differences in the type of humoral immune deficiencies, laboratory findings, and their susceptibility to develop different types of malignancies. One of them developed T cell acute lymphoblastic leukemia, isolated immunoglobulin A deficiency, and normal serum carcinoembryonic antigen (CEA) and carbohydrate antigen 19.9 (CA 19.9) levels. He expired at the age of nine years. The other, though a year older, has still got normal blood counts, normal immunoglobulin levels, and elevated serum CEA and CA 19.9 levels. Thus, insight into this disease is very important as AT patients require protection from unnecessary exposure to ionizing radiation to prevent malignancies. Diagnosis of AT allows appropriate genetic counseling for the family.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
