Flashcards

Down Syndrome

A genetic disorder caused by an extra copy of chromosome 21. It is characterized by physical features such as a flattened face, single crease across the palm of the hand, and intellectual disability.

Edwards Syndrome

A rare genetic disorder caused by an extra copy of chromosome 18. Infants with this syndrome often have severe heart defects, breathing problems, and developmental delays.

Patau Syndrome

A rare genetic disorder caused by an extra copy of chromosome 13. Individuals with this syndrome usually have severe physical and brain abnormalities, leading to a shortened lifespan.

Klinefelter Syndrome

A genetic disorder caused by an extra copy of the X chromosome in males (47, XXY). Individuals with this syndrome may have taller stature, learning difficulties, and decreased fertility.

Turner Syndrome

A genetic disorder caused by having only one X chromosome in females (45, XO). Individuals with this syndrome may have short stature, lack of ovarian development, and heart defects.

Study Notes

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.
