Variant Interpretation:
What is the protocol for interpreting a variation as a VUS? Help
Missense and silent changes that are unknown to HGMD database and to SNP databases (SNP137, 1000 genomes)

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

Will the lab re-contact the ordering physician if variant interpretation changes? Help
No.
Recommended fields not provided:
Technical Information
Test Confirmation: Help
Variations that are classified as pathogenic, probalbly pathogenic and variants of uncertain clinical significance are verified by Sanger sequencing
Availability: Help
Tests performed
Entire test performed in-house
Analytical Validity: Help
In house validation of the method has shown a sensitivity of 100 % (95% confidensinterval 95-100%) for regions with a sequencing depth of >X100.
Proficiency testing (PT):
Is proficiency testing performed for this test? Help
No
VUS:
Software used to interpret novel variations Help
Variants are analysed using SIFT, polyphen2, Align GVGD and MutationTaster for predictions. If possible we perform segregation analysis.

Laboratory's policy on reporting novel variations Help
The person who ordered the test will receive a written report by ordinary mail.
