PGT-M

PGT-M tests embryos for a single-gene condition known to run in the family, such as cystic fibrosis, sickle cell disease or Huntington's disease. It requires genetic counselling, confirmation of the family's exact gene change and a bespoke test built for that family before treatment starts, so the process takes months to prepare.

Also known as: PGD for monogenic disorders, single gene testing
