Triploid syndrome is an extremely rare chromosomal disorder. Individuals with triploid syndrome have three of every chromosome, i.e. a total of sixty-nine rather than the normal forty-six chromosomes.
Foetuses with triploid syndrome are usually lost through early miscarriage. However some infants have been born and survived as long as 10.5 months. Affected infants are usually small and have multiple birth defects. Those who survive are usually mosaic, meaning that some cells have the normal number of 46 chromosomes and some cells have 69. There are some people with Mosaic Triploidy who are in their 30s. There are only around 60 recorded cases ever in the world.
