Important Syndromes Due to Numerical Chromosomal Abnormalities

Trisomy of Autosomes: These syndromes result from an extra copy of an autosomal chromosome.
Trisomy 21 (Down Syndrome): A condition caused by an extra copy of chromosome 21.
Trisomy 18 (Edwards Syndrome): A severe syndrome due to an extra copy of chromosome 18.
Trisomy 13 (Patau Syndrome): Characterized by an extra chromosome 13. Often results in severe health problems and is often associated with early death.

Trisomy of Sex Chromosomes

Klinefelter Syndrome (47, XXY): A syndrome where males have an extra X chromosome. Causes reproductive and physical characteristics.
Triple X Syndrome (47, XXX): Females have an extra X chromosome. The additional X typically doesn't cause significant physical changes.

Monosomy

Turner Syndrome (45, XO): A sex chromosome disorder where females only have one X chromosome. This condition can affect physical development and reproductive capabilities.
