PGT-M
Preimplantation Genetic Testing For Monogenic Disorders
Preimplantation Genetic Testing (PGT-M) using NGS checks for single gene disorders when parents carry the condition and thus at risk of transmitting to their children. PGT-M allows us to select embryos free of a specific known disorders prior to implantation and pregnancy.
Possible candidates for PGD

Deafness (GJB2 gene)
Example of rare single genes disorders
Krabbe disease
Osteogenesis Imperfecta I
Kennedy’s disease
Mucopolysaccharidosis I
We also offer PGD for other single gene disorders which require personalized development.
