Sex chromosome abnormalities may be caused by full or partial deletions or duplications of sex chromosomes. Chromosomes are structures within cells that contain DNA and many genes. A gene is a segment of deoxyribonucleic acid DNA and contains the code for a specific protein that functions in one or more types of cells in the body see Genes and Chromosomes for a discussion about genetics. Genes contain instructions that determine how the body is supposed to function. Except for certain cells for example, sperm and egg cells or red blood cells , every human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes. There are 22 pairs of chromosomes that are not sex chromosomes called nonsex chromosomes, numbered chromosomes, or autosomal chromosomes and one pair of sex chromosomes.
