Test ID: MP3AK    
Mucopolysaccharidosis IIIA, Known Mutation

NY State Approved Indicates the status of NY State approval and if the test is orderable for NY State clients.

Conditional

Useful For Suggests clinical disorders or settings where the test may be helpful

Carrier testing of individuals with a family history of mucopolysaccharidosis type IIIA

 

Diagnostic confirmation of mucopolysaccharidosis type IIIA when familial mutations have been previously identified

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 mutation 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 IDReporting NameAvailable SeparatelyAlways Performed
FBCFibroblast Culture for Genetic TestYesNo
AFCAmniotic Fluid Culture/Genetic TestYesNo
MCCMaternal Cell Contamination, BYesNo

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 SGSH gene. If a familial mutation has not been identified, this known mutation test cannot be performed. To identify a familial mutation, order MP3AS / Mucopolysaccharidosis IIIA, 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 (non-confluent cultured cells) is received, amniotic fluid culture/genetic test will be added and charged separately. If chorionic villus specimen (non-confluent 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

Method Name A short description of the method used to perform the test

Polymerase Chain Reaction (PCR) Amplification/DNA sequencing are utilized to test for the presence of specific mutations in the SGSH gene previously identified in an affected family member.
(PCR is utilized pursuant to a license agreement with Roche Molecular Systems, Inc.)
