GYS1 Sequence Analysis
(Familial Mutation/Variant Analysis)
Test Information: Confirmation of Clinical Diagnosis - Known Familial Mutation(s), Carrier Testing - Known Familial Mutation(s)
Test Details
Test Code: 3836
Test Includes: Sequencing of the region(s) containing the familial alteration(s)

Special Notes: This test can only be performed if there is a previously identified familial mutation. A laboratory report containing the relative's mutation information, the specific biological relationship of this patient and the tested relative and the clinical status of this patient (symptomatic or asymptomatic) must be submitted with the specimen. If the original familial mutation was identified in another laboratory, this testing must be discussed with one of our genetic counselors prior to sending a specimen.
