Genetics
PGT-M is used where a couple carries a known genetic condition such as cystic fibrosis, Huntington disease or a BRCA variant. It requires a genetic counselling assessment and a bespoke test built from family samples, which takes weeks to months to prepare.
Also known as: PGD, single gene testing, monogenic testing
