INTRODUCTION.
T-cell acute lymphoblastic leukemia (T-ALL) is a type of acute lymphoblastic leukemia characterized by an aggressive malignant neoplasm of the bone marrow. Acute lymphoblastic leukemia (ALL) is a condition, wherein immature white blood cells accumulate in the bone marrow and crowd out normal white blood cells. Accumulation in the liver, spleen, and lymph nodes frequently occurs as well. A chromosomal aberration involving the TCTA gene is associated with T-cell acute lymphoblastic leukemia (T-ALL) is the translocation t(1;3)(p34;p21).
There is evidence T-cell leukemia translocation associate (TCTA) gene is encoded on cytogenetic location 3p21.31 and genomic coordinates 3:49,412,423-49,416,476. The screenshot of the TCTA gene 4,054 bp (base pairs) of DNA sequence length is shown BELOW. Nine (9) other genes besides TCTA in the 3p21.31 cytogenetic location are listed BENEATH.
