Question

What is thymic aplasia also known as?

1) DiGeorge syndrome
2) Turner syndrome
3) Williams syndrome
4) Klinefelter syndrome

Answer 1

Thymic aplasia is also known as DiGeorge syndrome, which includes a range of symptoms from heart defects to immune system issues. It is distinct from other chromosomal disorders like Down syndrome (triplication of chromosome 21) and Turner syndrome (monosomy X).

Step-by-step explanation:

Thymic aplasia is also known as DiGeorge syndrome. Symptoms associated with DiGeorge syndrome may include heart defects, poor immune system function, complications related to hypocalcemia, developmental delays, and behavioral problems. Other genetic disorders can show overlapping symptoms, such as Williams syndrome or Turner syndrome, but they have different genetic origins. For example, whereas Down syndrome is due to nondisjunction leading to an extra chromosome 21, Turner syndrome is the result of having only one X chromosome (monosomy). Furthermore, Klinefelter syndrome is a condition denoted by the genotype XXY.
