QUICK Analysis

Test Information

The QUICK Analysis is Greenwood's free NGS-reflex analysis that rapidly screens full exome data for pathogenic alterations when panel results are negative.  The QUICK Analysis increases the yield of cost-effective gene panel tests. By screening variants based on molecular criteria first and reviewing the phenotype second, QUICK is good at picking up new or poorly characterized genes.  While the QUICK Analysis is not as thorough as a whole exome analysis, we have found it effective in expediting a diagnosis for a growing number of patients.

Cost

Reflex analysis done at no charge following next generation sequencing test.

Indications

The QUICK Analysis is available for patients who have had normal NGS-based testing at the Greenwood Diagnostic Laboratory.

Methodology

All NGS testing at our lab is run on an exome backbone, so whole exome data is available for every patient who has a panel. We have designed a stringent filtering system to "QUICKly" sort and review variants that are highly likely to explain the patient's phenotype. Only pathogenic or likely pathogenic alterations will be reported. Secondary findings genes are excluded from this analysis unless indicated by the patient's phenotype.

Detection

Depending on the patient's clinical features and the initial testing, the lab has identified the causative variant in 10-50% of cases analyzed by QUICK Analysis.

Variants reviewed during the QUICK Analysis must be rare in the general population and meet out quality thresholds regarding depth of sequence coverage and allele frequency. Variants must fall into one of the following categories:
-Previously reported in the Human Gene Mutation Database (HGMD)
-Causes a frame shift, stop gain, start loss or stop loss effect on the encoded protein
-Expected to affect a splice site at the +/- 1 or 2 position
-Compound heterozygous variant in a gene associated with an autosomal recessive disorder

A complete secondary findings analysis is NOT included as part of the QUICK Analysis; however, a variant in one of these genes may be reported if it is a good match for the patient's phenotype.

Specimen Requirements

No additional specimen needed. QUICK Analysis will be done using existing NGS data from previous testing.

Unexpected. If there is a term that sums up life it could very well be: unexpected. Life is full of unexpected moments. Some of these moments can be full of unexpected blessings while others may be full of unexpected obstacles. However, sometimes the unexpected can be both an obstacle and blessing at the same time; you just need someone to help you see both sides. The Greenwood Genetic Center is a place that helps shed some light on the...
