Variant Interpretation:
What is the protocol for interpreting a variation as a VUS? Help
Variant is excluded as a known SNP by searching databases e.g. gnomAD, dbSNP, 1000 Genome etc. In silico analysis is performed to assess probability of variant being pathogenic. Assessment of whether the variant co-segregates with the disease phenotype where possible. ACMG guidelines for variant analysis used.

Are family members with defined clinical status recruited to assess significance of VUS without charge? Help
Yes. Where possible.

Will the lab re-contact the ordering physician if variant interpretation changes? Help
Yes. If significant.

Clinical validity, Target population, Is research allowed on the sample after clinical testing is complete?, Sample negative report, Sample positive report
Technical Information
Test Procedure: Help
Results are confirmed on an independent amplification & sequence from the primary sample - where possible in the alternate direction.
Test Confirmation: Help
Results are confirmed on an independent amplification & sequence from the primary sample - where possible in the alternate direction.
Availability: Help
Tests performed
Entire test performed in-house
Analytical Validity: Help
Analysis of entire coding and immediate flanking regions should provide a >95% sensitivity - based on current knowledge. Reflex testing for possible large deletions is possible where indicated.
Proficiency testing (PT):
Is proficiency testing performed for this test? Help
No
VUS:
Software used to interpret novel variations Help
Alamut and others available on-line e.g. PMut Varsome and Franklin used for variant analysis

Laboratory's policy on reporting novel variations Help
Interpretation of in silico analysis is included on the report. ACMG guidelines for variant analysis used.
