Clinical Information

Test purpose:

Diagnosis; Pre-symptomatic; Therapeutic management

Target population:

The Invitae Hypopigmentation Panel analyzes genes that are associated with hypopigmentation, which is characterized by decreased skin, hair, and/or eye pigmentation. These genes were selected based on the available evidence to date to provide a broad analysis for inherited hypopigmentation. The genetic heterogeneity associated with these conditions can make it … View more

Variant Interpretation:

What is the protocol for interpreting a variation as a VUS?
Invitae's variant interpretation methodology adheres closely to ACMG guidelines. Observed variants are interpreted according to the framework of evidence recommended by these guidelines, based on evidence in peer-reviewed literature and Invitae's database. Our clinical report documents the evidence and logic supporting each variant interpretation to make it easy for the … View more

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

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

Recommended fields not provided:

Clinical validity, Clinical utility, Is research allowed on the sample after clinical testing is complete?, Sample negative report, Sample positive report

Our sequence analysis covers clinically important regions of each gene, including coding exons and 10 to 20 base pairs of adjacent intronic sequence on either side of the coding exons in the transcript listed below. In addition, the analysis covers the select non-coding variants specifically defined in the table below. Any variants that fall outside these regions are not analyzed. Any limitations in the analysis of these genes will be listed on the report. Contact client services with any questions. Based on validation study results, this assay achieves >99% analytical sensitivity and specificity for single nucleotide variants, insertions and deletions <15bp in length, and exon-level deletions and duplications. Invitae's methods also detect insertions and deletions larger than 15bp but smaller than a full exon but sensitivity for these may be marginally reduced. Invitae’s deletion/duplication analysis determines copy number at a single exon resolution at virtually all targeted exons. However, in rare situations, single-exon copy number events may not be analyzed due to inherent sequence properties or isolated reduction in data quality. Certain types of variants, such as structural rearrangements (e.g. inversions, gene conversion events, translocations, etc.) or variants embedded in sequence with complex architecture (e.g. short tandem repeats or segmental duplications), may not be detected. Additionally, it may not be possible to fully resolve certain details about variants, such as mosaicism, phasing, or mapping ambiguity. Unless explicitly guaranteed, sequence changes in the promoter, non-coding exons, and other non-coding regions are not covered by this assay. Please consult the test definition on our website for details regarding regions or types of variants that are covered or excluded for this test. This report reflects the analysis of an extracted genomic DNA sample. In very rare cases, (circulating hematolymphoid neoplasm, bone marrow transplant, recent blood transfusion) the analyzed DNA may not represent the patient's constitutional genome. View more
