PGT for Monogenic Disorders (PGT-M) is applied to prevent certain genetic diseases to be inherited to the child from one or both parents which are identified to be carriers of a mutation in a single gene. PGT-M was formerly known as Preimplantation Genetic Diagnosis (PGD).
Who should undergo PGT-M
Only couples with a known genetic mutation in the family that can be inherited to their offspring should perform this testing. Examples of inherited genetic diseases that can be identified with PGT-M are: Thalassemia, Cystic Fibrosis, Tay-Sachs disease etc.
