*If prior authorization is not submitted, test may be delayed.
Test Overview
The coding exons and flanking consensus splice sites of the IDUA gene are amplified using specific primers, and bidirectionally sequenced using a fluorescent method.
Analysis for the presence of IDUA (OMIM:252800) variants in patients with Mucopolysaccharidosis type I (MPS I).
Interpretive report provided.
This assay will not detect large deletions in the IDUA gene or intronic mutations outside the region sequenced in the IDUA gene.

Specimen Requirements
Collect specimen in a lavender top tube. Send intact specimen within 24 hours if stored at room temperature or within 5 days if stored refrigerated. Include the patient's family history, pedigree, and ethnicity on the test requisition. Obtaining informed consent from the patient prior to genetic testing is strongly recommended. If desired, a UMHS Request and Consent for Genetic Testing form can be obtained from the MMGL Molecular Genetics Laboratory by contacting the MLabs Client Services Center at 800-862-7284 or online at https://mlabs.umich.edu/sites/default/files/2020-01/file/pci-mmgl_infor….
