Myriad Foresight® carrier screen spotlight
CYP21A2-Related (21-OH CAH)
Congenital adrenal hyperplasia (CAH) is a family of conditions affecting hormone levels. The most common form of CAH, 21-hydroxylase-deficient congenital adrenal hyperplasia (21-OH CAH), is caused by mutations in the CYP21A2 gene. Symptoms of 21-OH CAH include:
“My pediatrician told me that if I didn’t bring my son in… we likely would have lost him.”
Michèle, carrier for 21-OH CAH
Although her son Maris (age 6) appeared healthy after birth, a few days later Michèle could tell something was wrong. She first heard about CAH when her son was being treated in the emergency room, and is passionate about ensuring families have access to information that could prove vital in saving their child’s life.
Advance knowledge of hereditary conditions like 21-OH CAH can inform life-saving intervention after birth and prevent the diagnostic odyssey, saving years of stress, anxiety and cost
21-OH CAH is similar in incidence to spinal muscular atrophy, for which universal screening guidelines exist
Due to technical challenges, 21-OH CAH is absent from most expanded carrier screening panels
As one of the pioneers in clinical next generation sequencing (NGS) and one of the largest sequencing facilities in the world, Myriad Genetics’ CLIA laboratory has tested over one million samples. With a relentless dedication to qualify and passion for providing the best care to our patients, we have developed a new paradigm of precision manufacturing at scale.
The Foresight Carrier Screen is methodically designed to maximize the detection of couples at-risk for a pregnancy affected by serious, prevalent inherited conditions such as 21-OH CAH.³
In total, ~1 in 300 pregnancies are affected by a condition on the Foresight Carrier Screen.²
21-OH CAH is absent from most carrier screening panels because it is technically challenging to test for and requires more advanced analysis to avoid false positives and false negatives. Myriad’s custom assay for 21-OH CAH maximizes detection rates that give you the utmost confidence in every result.
“I’ve always said that if you can name it, you can do something about it.”
