@ysmina-- I'm sure that's possible. I have heard of people doing genetic testing in the first two months of pregnancy if there is a risk of a genetic risk in their family. And you would have the option to terminate the pregnancy if it turns out that there is.
But a safer, and according to some, more ethical approach would be genetic testing before conception. The man and woman can both get genetic testing to see if there is anything abnormal. Genetic testing can also be done during in vitro fertilization to make sure that a healthy embryo implants in the womb.
Even though many people think that trisomy 15 happens based on chance, I don't think that's true. There are studies which showed that the sperm of fathers of children with Angelman syndrome carried multiple copies of genes which is more than likely the cause of the syndrome.
Of course people can't know if they carry this risk until something happens. But women who have trisomy 15 miscarriage should try again with assistance from medical professionals and with genetic testing during the process.
