Single Gene Disorder Testing (PGD)
Single gene disorders are genetic conditions caused by a mutation of a specific gene. Single gene disorders are often heritable (they run in families), and therefore, individuals with a family history of a single gene disorder may be at risk for passing the condition onto their children. Examples of some common single gene disorders include:
Cystic fibrosis (CF)
Sickle cell anemia
Duchenne muscular dystrophy (DMD)
Fragile X syndrome
Spinal muscular atrophy

Three easy steps to PGD success
Aster IVF is one of the early adapters using next generation sequencing (NGS) technology for preimplantation genetic diagnosis (PGD). NGS is far superior to real-time PCR techniques that are the current standard.
Next generation sequencing (NGS) combines the power of single mutation detection and complete 24-chromosome aneuploidy screening. Both tests are performed simultaneously on the same embryo.
More about PGD
Preimplantation genetic diagnosis (or PGD) is a testing procedure used when either parent has been diagnosed with a genetic abnormality. Testing is performed on the embryos to determine if they are carriers of the genetic abnormality before implantation.
Aster IVF can test embryos for single gene disorders prior to implantation and select only embryos that are free of genetic defects. PGD is available for a large number of genetic disorders such as:
Spinal muscular atrophy type 1
Sickle cell disease
Fragile X syndrome
Duchenne muscular dystrophy
And more (View our list of genetic disorders here)
PGD is recommended when parents are likely to transmit a known genetic disorder to their children. Once PGD is performed, only healthy embryos free of genetic defects are transferred into the mother’s uterus. This procedure greatly reduces the risk of the child inheriting a genetic disorder and of late pregnancy termination.
PGD testing is performed for 3 major categories of genetic disorders:
Single gene defects
PGD or PGS?
Preimplantation genetic screening (PGS) (Link to PGS page) is used to perform a general screening of embryos and does not look for a specific disease. PGS uses PGD techniques and technology to identify embryos at risk.
