Sex chromosome aneuploidies (SCA) occur when there are changes in the expected number of the chromosomes associated with sex, the X and Y chromosomes. The most common sex chromosome aneuploidies are Klinefelter syndrome, Triple X syndrome, Jacob’s syndrome and Turner syndrome.

Aneuploidy is the presence of chromosome number that is different from the simple multiple of the basic chromosome number. An organism which contains one or more incomplete chromosome sets is known as aneuploid. Aneuploidies are classified in two ways: Depending on the chromosome type that is affected: sexual or autosomal. Sexual chromosome aneuploidy and autosomal Depending on the number of extra or missing chromosomes: Nullisomy: a pair of homologous chromosomes is missing. Nullisomy: a pair of Aneuploidy: Extra or missing chromosomes Changes in a cell's genetic material are called mutations. In one form of mutation, cells may end up with an extra or missing chromosome.
