What are chromosomal abnormalities?
Human beings have 23 pairs of chromosomes (46 chromosomes in total), DNA strands and proteins containing the genetic information needed for the body to form and function.
Chromosomal abnormalities are conditions in which the number and/or structure of chromosomes may differ from the normal arrangement. Specifically, trisomies are conditions in which the individual has three copies of the same chromosome instead of the usual two. For example, Trisomy 21 involves the presence of three copies of chromosome 21, a condition associated with the well-known Down’s syndrome.
Early detection of the presence of a chromosomal abnormality allows parents-to-be to plan appropriate obstetrical-gynaecological management of both the continuation of pregnancy and childbirth.
