Well it’s not a short list of genetic disorders. I think there are some chromosomal abnormalities that are responsible for miscarriage. So chromosomal abnormalities can cause miscarriage and I would say that single autosomal trisomies would be perhaps the main causes of miscarriage. The communist is a trisomy 16 which happens in about 18% of miscarriages, trisomy 22 is another cause of miscarriage and trisomy 21 which is the Down syndrome is another cause of miscarriage. So there are some specific chromosomal abnormalities that would be linked with an increased risk of miscarriage.
