Numerical abnormalities are one type of chromosome abnormality. These type of birth defects occur when there is a different number of chromosomes in the cells of the body than is usually found. So, instead of the usual 46 chromosomes in each cell of the body, there may be 45 or 47 chromosomes. Having too many or too few chromosomes is a cause of some birth defects.
