Diagnosis Chromosomal Abnormality patient's problems are due to something other than an abnormal number of chromosomes. one or more extra sex chromosomes (i.e., XXY) Normal # of chromosomes Klinefelter's Syndrome Down's Syndrome Trisomy 21, extra chromosome 21 Trisomy 13 Syndrome extra chromosome 13 Interpreting the karyotype Lab technicians compile karyotypes and then use a specific notation to characterize the karyotype. This notation includes the total number of chromosomes, the sex chromosomes, and any extra or missing autosomal chromosomes. For example, 47, XY, +18 indicates that the patient has 47 chromosomes, is a male, and has an extra autosomal chromosome 18. 46, XX is a female with a normal number of chromosomes. 47, XXY is a patient with an extra sex chromosome.
