(Trisomy D Patau Syndrome)
Trisomy 13 is caused by an extra chromosome 13 and is composed of an abnormality in the frontal lobe, the midface, eye development, a mental retardation, heart defects and a small birth size.
Trisomy 13 occurs in about 1 in 10,000 live births, about 80% of cases there is a complete trisomy 13. An increasing maternal age increases the risk. The extra chromosome is usually maternal origin.
