Test purpose: Help
Diagnosis; Pre-symptomatic; Screening
Clinical validity: Help
This panel should be performed in all individuals suspected of having an overlapping clinical phenotype. Confirmation of a clinical diagnosis through genetic testing can allow for genetic counseling and may direct medical management. Genetic counseling can provide a patient and/or family with the natural history of the condition, identify at-risk … View more
Variant Interpretation:
What is the protocol for interpreting a variation as a VUS? Help
The interpretation of a variation as a VUS is done according to the practice guidelines provided by the American College of Medical Genetics (ACMG; ACMG recommendations for standards for interpretation and reporting of sequence variations).

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
Yes. In case of identification of mutation that can be present in non-affected family members, or after identification of highly specific genetic change, or in additional special situations we could contact the ordering again

Entire test performed in-house
Analytical Validity: Help
CENTOGENE has established stringent quality criteria and validation processes for variants detected by NGS. Variants with low sequenci ng quality and/or unclear zyg osity are confirmed by orthogonal methods. Consequently, a specificity of > 99.9% for all reported variants is warranted. Mitochondrial variants are reported for heteroplasmy levels of 15% … View more

CentoMD®, ALAMUT, integrating other programs (Polyphen-2, Mutation Tester, Alignment, ExPASy, BLAST)

Laboratory's policy on reporting novel variations Help
Centogene has a common practice to report all variants found in genetic testing, including novel and previously reported variants. A number of criteria are used to support a variant as being potentially disease-causing, including segregation with disease status in other affected family members, absence from a control population, and location … View more
