Carrier screening, before or during pregnancy, can help determine the risk of having a child with a genetic disorder. The American College of Obstetricians and Gynecologists (ACOG) recommends that all women be offered pre/post-conception carrier screening for cystic fibrosis and spinal muscular atrophy. Additionally, ACOG supports carrier screening for other disorders based on the patient’s medical and family history.

CTGT offers several options for carrier screening, including single disorder tests and multiple disorder panels. Full gene sequencing and large deletion/duplication analysis is performed for these carrier tests to obtain the highest sensitivity regardless of ethnic background. Spinal muscular atrophy testing includes assessment of SMN1/2 copy number and silent carrier risk. Fragile X testing include determination of the number of CGG repeats in the 5’UTR of FMR1.
