Background Information for Ashkenazi Jewish Diseases (BLM, ASPA, IKBKAP, FANCC, GBA, MCOLN1, SMPD1, HEXA), Common Mutation Panel:
Autosomal recessive.
Clinical Sensitivity:
99 percent for Canavan, Familial Dysautonomia and Fanconi Anemia Group C; 95 percent for Bloom, Mucolipidosis IV and Niemann-Pick type A; 94 percent for Tay-Sachs, and 90 percent for Gaucher.
Multiplex polymerase chain reaction and Detection Primer Extension.
Analytical Sensitivity and Specificity:
99 percent.
: Mutations, other than those tested on this panel, will not be detected. Diagnostic errors can occur due to rare sequence variations.

See Compliance Statement C:
Statement C: The performance characteristics of this test were validated by ARUP Laboratories. The U.S. Food and Drug Administration (FDA) has not approved or cleared this test; however, FDA approval or clearance is currently not required for clinical use of this test. The results are not intended to be used as the sole means for clinical diagnosis or patient management decisions. ARUP is authorized under Clinical Laboratory Improvement Amendments (CLIA) and by all states to perform high-complexity testing.
