7MOLECULAR KARYOTYPING FOR AMNIOTIC FLUIDAll Chromosomal aneuploidies (46 chromosomes)Luminex solid phase assayAmniotic fluid (10 to 12 ml) / Chorionic villi sample (CVS)10 daysFetal DNA to identify specific gene mutations and diagnose a variety of inherited diseases. Each test is ordered separately based upon the parents' personal and family histories. If a specific gene mutation is known to be present in the mother's or father's family, then that specific gene mutation can be tested for. While there are hundreds of genetic tests that can be performed, only a few are associated with relatively common disorders. Typically, only the most common mutations are tested; therefore, a fetus could still have an inherited disorder even though genetic testing did not identify one.
8Y-Chromosome MicrodeletionPCRWhole blood 3ml in EDTA vacutainer5 daysYq microdeletions involving some or all of the azoospermic factor (AZF) region are the most frequently identified cause of spermatogenic failure in chromosomally normal men with nonobstructive azoospermia (3%-15%) or severe oligospermia (6%-10%). Among unselected infertile males, the overall frequency of Yq microdeletions is approximately 3%. The relative frequency of Yq microdeletions makes the evaluation for them an important aspect of the diagnostic work up in infertile males, especially those with azoospermia or severe oligospermia. Most cases of Yq microdeletions occur de novo, and due to the consequential infertile phenotype, they are typically not transmitted. However, in cases where assisted reproductive technology (example: testicular sperm extraction followed by intracytoplasmic sperm injection) is used to achieve viable pregnancy, all male offspring born to a microdeletion carrier will carry the deletion and may be infertile. Men testing positive for 1 or more microdeletions who are enrolled in an in vitro fertilization treatment program may wish to consider alternative options to intracytoplasmic sperm injection (eg, donor sperm) and consultation with an experienced reproductive endocrinologist and medical geneticist is recommended. Most Y microdeletions are the result of homologous recombination between repeated sequence blocks. Testing for deletions involves investigating for the presence or absence of markers located within nonpolymorphic
regions of the AZF region.

Specimen at room temperature. Also acceptable: Refrigerated. Ship in cooled container during summer months.20Clinical exome sequencing (CES) is rapidly becoming a common molecular
diagnostic test for establishing a definitive molecular diagnosis of individuals with rare genetic disorders which can allow for:
-Better understanding of the natural history/prognosis
-Targeted management (anticipatory guidance, management changes, specific therapies)
-Predictive testing of at-risk family members
-Testing and exclusion of disease in siblings or other relatives
-Recurrence risk assessment
-Reproductive decision-making
Serving as a second-tier test for patients in whom previous genetic testing for specific syndromes was negative Providing a potentially cost-effective alternative to establishing a molecular diagnosis compared to multiple independent molecular assays

16Pre-implantation Genetic DiagnosisTargeted identified mutation detection in Trophoblast cellPCR and Sanger SequencingTrophoblast cell20-25 daysPreimplantation genetic diagnosis (PGD) is a procedure that allows embryos to be tested for genetic disorders before they enter the uterus and before pregnancy has begun. Embryos obtained by in vitro fertilization undergo a biopsy procedure in which one or two cells are removed and tested for a specific disorder. If the cell is unaffected, the embryo from which it was taken is judged to be free of the disorder.
