X-Linked Adrenoleukodystrophy, Known Mutation
NY State Approved Indicates the status of NY State approval and if the test is orderable for NY State clients.
Confirming a diagnosis of X-linked adrenoleukodystrophy when a familial mutation has previously been identified
Carrier screening of at-risk individuals when a mutation in the ABCD1 gene has been identified in an affected family member
Genetics Test Information Provides information that may help with selection of the correct test or proper submission of the test request
Documentation of the specific familial mutations must be provided with the specimen in order to perform this test.
Reflex Tests Lists test(s) that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial test(s)
|Test ID||Reporting Name||Available Separately||Always Performed|
|FBC||Fibroblast Culture for Genetic Test||Yes||No|
|AFC||Amniotic Fluid Culture/Genetic Test||Yes||No|
|MCC||Maternal Cell Contamination, B||Yes||No|
Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
This test is for known mutations in the ABCD1 gene. If a familial mutation has not been identified, this known mutation test cannot be performed. To identify a familial mutation, order XALDS / X-Linked Adrenoleukodystrophy, Full Gene Analysis.
If skin biopsy is received, fibroblast culture for genetic test will be added and charged separately.
For prenatal specimens only: If amniotic fluid (nonconfluent cultured cells) is received, amniotic fluid culture/genetic test will be added and charged separately. If chorionic villus specimen (nonconfluent cultured cells) is received, fibroblast culture for genetic test will be added and charged separately. For any prenatal specimen that is received, maternal cell contamination studies will be added.
Special Instructions and Forms Describes specimen collection and preparation information, test algorithms, and other information pertinent to test. Also includes pertinent information and consent forms to be used when requesting a particular test
Polymerase chain reaction (PCR) amplification/DNA sequencing are utilized to test for the presence of specific mutations in the ABCD1 gene previously identified in an affected family member.
