Clinical Testing/Confirmation of Mutations Identified Previously
    Comment: Includes next-generation sequencing and copy number variation studies (deletion/duplication studies).
Test additional service: Help
Custom mutation-specific/Carrier testing
Test development: Help
Test developed by laboratory (no manufacturer test name)
Informed consent required: Help
Based on applicable state law
Test strategy: Help
The Usher Panel uses custom-targeted sequence capture for DNA enrichment followed by massively parallel DNA sequencing. Data analysis is performed and results are discussed at a multidisciplinary meeting where each patient's variants are discussed individually and in the context of their unique clinical information to provide the most comprehensive diagnosis … View more

Variant Interpretation:
Are family members with defined clinical status recruited to assess significance of VUS without charge? Help
No.

Will the lab re-contact the ordering physician if variant interpretation changes? Help
Not provided.
Recommended fields not provided:
Clinical validity, Clinical utility, What is the protocol for interpreting a variation as a VUS?, Will the lab re-contact the ordering physician if variant interpretation changes?, Is research allowed on the sample after clinical testing is complete?, Sample negative report, Sample positive report
Technical Information
Test Procedure: Help
targeted genomic enrichment and massively parallel sequencing
Test Platform:
None/not applicable
Test Confirmation: Help
We have shown experimentally variants with QD >10 do not require Sanger sequencing validation (PMID: 21078986). In cases where the QD is between 5 and 10 and/or the zygosity status is indeterminate, Sanger confirmation is performed. Quality control testing to detect specimen mislabeling or sample contamination (sample integrity check) is … View more
Availability: Help
Tests performed
Interpretation performed in-house
Report generated in-house
Specimen preparation performed both in-house and at an outside lab
Wet lab work performed in-house

Test performance comments
DNA isolation from whole blood can be performed by the ordering healthcare provider's institution and/or send-out laboratory and DNA sent to MORL for testing.
Analytical Validity: Help
greater than 99%
Proficiency testing (PT):
Is proficiency testing performed for this test? Help
Yes

Method used for proficiency testing: Help
Alternative Assessment

PT Provider: Help
European Molecular Genetics Quality Network, EMQN

Description of PT method: Help
In addition to formal proficiency testing with EMQN, MORL performs in-house proficiency testing.
