Down syndrome
or trisomy 21 Congenital disorder caused by an extra chromosome (trisomy) on the chromosome 21 pair. Those with the syndrome may have broad, flat faces; up-slanted eyes, sometimes with epicanthal folds (whence its former name, mongolism); mental retardation (usually moderate); heart or kidney malformations; and abnormal fingerprint patterns. Many persons with Down syndrome can live and work independently or in a sheltered environment, but they age prematurely and have a short (55-year) life expectancy. The risk of bearing a child with the disorder increases with the mother's age; it can be detected in the fetus by amniocentesis

down syndrome
The most common malformation caused by trisomy 21 Most of the patients (95%) have complete trisomy of chromosome 21; some have translocation or mosaic forms The phenotype is diagnostic (short stature, characteristic facial appearance, mental retardation, brachydactyly, atlanto-axial instability, thyroid and white blood cell disorders) Congenital heart defects are frequent, atrioventricular septal defect and ventricular septal defect being the most common Mitral valve prolapse and aortic regurgitation may be present Down syndrome patients are prone to earlier and more severe pulmonary vascular disease than might otherwise expected as a consequence of the lesions identified
down syndrome
Human cells usually contain 46 chromosomes which carry the genes that are responsible for all our inherited characteristics In Down Syndrome, the cells usually contain not 46, but 47 chromosomes; with the extra chromosome being a number 21 This excess genetic material, in the form of additional genes along the 21st chromosome, results in Down Syndrome Because 95 percent of all cases of Down Syndrome occur because there are three copies of the 21st chromosome, it is referred to as "trisomy 21 "
