Definition of A (adenine)

A (adenine): In genetics, A stands for adenine, one member of the A-T (adenine-thymine) base pair in DNA.
In DNA, the code letters are A, T, G, and C, which stand for the chemicals adenine, thymine, guanine, and cytosine, respectively. In DNA base pairing, adenine always pairs with thymine, and guanine always pairs with cytosine. Adenine is also one of the bases in RNA. There it always pairs with uracil (U). The base pairs in RNA are therefore A-U and G-C.

Definition of A-T

A-T: Ataxia-telangiectasia
A progressive neurodegenerative genetic disease characterized by cerebellar ataxia (incoordination and lack of balance), ocular telangiectasia ("red eyes" due to widening of small blood vessels in the conjunctiva), immune defects, and a predisposition to malignancy. Chromosomal breakage is a feature. Ataxia-telangiectasia (A-T) cells are abnormally sensitive to killing by ionizing radiation.
A-T becomes evident in early childhood, usually in the first decade of life. The signs of A-T are

lack of balance and slurred speech (due to the ataxia) and telangiectasias (tiny red "spider" veins), which appear in the whites of the eyes or on the surface of the ears and cheeks.
People with A-T are predisposed to leukemia and lymphoma. They are also extremely sensitive to radiation exposure. Most people with A-T have a defective immune system, making them susceptible to recurrentrespiratory infections. Other features of the disease may include diabetes mellitus, premature graying of the hair, difficulty swallowing and slowed growth.
There is no cure for A-T and, currently, there is no known therapy to slow the progression of the disease. Treatment is symptomatic and supportive. Physical and occupational therapy may help maintain flexibility. Speech therapy may also be useful. Intravenous immune globulin (IVIG)
