The purpose of this study is to find genetic causes of recurrent pregnancy loss (RPL). RPL is defined by two or more miscarriages under 20 weeks gestation and affects approximately 5% of women.The causes of RPL are not well understood. After all the currently recommended testing for RPL has been done, about half of women with RPL will still have no identifiable cause. This lack of knowledge makes it difficult to provide effective medical care for couples with RPL.This study will compare reading about 20000 genes in the entire human genetic library by whole genome sequencing in the miscarriage material and also your and your partner’s DNA from blood samples. The DNA in a person is a combination of the DNA from each of their biological parents. If you have healthy children we may ask your consent for them to give a blood sample for DNA extraction and testing. Similarly, we may ask the same for other family members such as grandparents if necessary. We may also request your permission to use stored DNA or miscarriage material from previous pregnancy loss if available. Testing of family members or previous miscarriage materials may help to understand DNA sequence variants or changes identified in the miscarriage sample.

There will be a one time collection of blood samples.
