The Amish Genetic Disease Panel, now known as Genetic Awareness Panel (GAP), was developed to address what is often an expensive and lengthy diagnostic odyssey for clinicians treating patients of Amish descent. GAP distills and leverages our nearly twenty years of experience identifying, diagnosing, and treating families affected by rare genetic disorders.
There are more than 120 disorders for which a common Amish founder variant has been reported in the medical literature. GAP tests for all published, population specific gene variants for these disorders.
The Genetic Awareness Panel can be used for efficient diagnoses, supplemental newborn screening, and carrier testing for individuals of Amish heritage.
Efficient Diagnosis
The Genetic Awareness Panel analyzes more than 120 founder mutations common to the North American Amish populations in one test. Results for more than 120 founder mutations are available in a few weeks at a relatively inexpensive cost to the patient.
Supplemental Newborn Screening
The Genetic Awareness Panel is a critical supplement to state newborn screening for high risk families with Amish ancestry. DNA based testing does not require confirmatory testing, as does newborn screening, which allows for faster diagnoses and prompt treatment of affected newborns. Our panel covers additional conditions that are not covered on state newborn screening, providing the most comprehensive genetic screening possible for our Amish families.
Carrier Testing
The Genetic Awareness Panel can be used to provide risk information to interested Amish adults, most of whom are carriers for several disorders. Test results will assist parents and clinicians in future testing recommendations for at risk children or other family members.
Sample Collection and shipping
Requires 3-5 ml whole blood or cord blood in a purple top (EDTA) tube; 2-3 ml for infants and children under two. Sample should be refrigerated until shipped. Ship by overnight delivery or courier, protecting sample from temperature extremes.
Cost and turn-around time
Cost: $450. Test results available within 4 to 6 weeks.
