__Patau's Syndrome__ Also known as trisomy 13, patau syndrome has an extra chromosome found in the 13th pair of its karyotype.

Patau syndrome is recognized at birth by mosty body defects and nurologic performance. The major defects found in children and their reason for death is severe neurologic and heart defects which make it very difficult for infants to survive. Patau's Syndrome is the least common and most severe of all off the autosomal trisomies. The frequency in the united states is one case for every 8,000-12000 live births. The only cause of the syndrome that can be somewhat helped is age of the mother. The older the mother is increases the chances for the extra 13th chromosome.Patau syndrome can also happen when part of the 13th chromosome becomes attached to another chromosome (or translocation), before or at conception. Affected people have two copies of the 13th chromosome, plus extra material from the 13th chromosome is attached to another chromosome. With translocation, the person has a partial trisomy for chromosome 13 and often the physical signs of the syndrome differ from Patau syndrome. There are no solutions for or treatments for Patau's syndrome but at birth if it is necessary surgery can be performed for heart defects or cleft lip. Generally these surgeries are not performed because infants are not expected to last long. .
