Diagnosis;
Risk Assessment
Clinical validity:
Help
This test is a full gene sequence analysis of the IDUA gene that sequences the entire protein coding regions (exons) as well as splice sites (exon-intron junctions).
Target population:
Help
Individuals suspected to have mucopolysaccharidosis type I (MPS I).
Variant Interpretation:
What is the protocol for interpreting a variation as a VUS?
Help
VUS and novel variants will be interpreted by trained variant analysis team member and a lab director using the current ACMG variant classification criteria.
VUS and novel variants will be interpreted by trained variant analysis team member and a lab director using the current ACMG variant classification criteria.
Are family members with defined clinical status recruited to assess significance of VUS without charge?
Help
No.
No.
Will the lab re-contact the ordering physician if variant interpretation changes?
Help
Yes. No systemic re-evaluation of previously reported variants/findings are currently performed. However, if the same variant/finding is identified in another patient and current assessment results in change in variant classification/interpretation, then the laboratory will recontact the ordering provider and issue an updated report.
