Exome Subpanel Test

Description

A targeted bioinformatic masking process is applied to next generation sequencing data to limit analysis to a defined set of genes. Panel-on-Demand for ordering a custom set of genes is available, as well as predefined gene panels. The test includes deletion/duplication (del/dup) analysis for all genes in the selected panel. These options allow for either efficient ordering of predefined panels or gene sets customized for a wide range of clinical indications; both approaches offer panel testing while supporting future broader testing options without the need for resequencing.

We offer several options for Panel-on-Demand based on the number of genes that will be tested.

  • Hyper Panel on Demand (201-500 genes)
  • Super Panel on Demand (101-200 genes)
  • Mega Panel on Demand (11-100 genes)
  • Micro Panel on Demand (2-10 genes)
  • Single Gene Sequencing

Use the web tool at Exome Panel-on-Demand Generator to generate a 6-character code for a custom panel.

Predefined panels are also ordered using the EXPNL test code. For an overview of predefined gene panels, please see EXPNL Predefined Panels Guideline.

Our predefined gene panels include:

The Comprehensive Cardiac Panel - Cardiomyopathy indication is appropriate when a hereditary cause is suspected for a diagnosis of cardiomyopathy, such as Hypertrophic Cardiomyopathy, Dilated Cardiomyopathy, or Arrhythmogenic Cardiomyopathy, whether an isolated finding or presenting as part of a syndrome, such as in Noonan syndrome, muscular dystrophies, or metabolic storage diseases.

The Comprehensive Cardiac Panel - Arrhythmia indication is appropriate when a hereditary cause is suspected for a diagnosis of arrhythmia, such as Brugada syndrome, Long QT syndrome, Short QT syndrome, Catecholaminergic Polymorphic Ventricular Tachycardia, or Arrhythmogenic Cardiomyopathy.

The Pulmonary Arterial Hypertension (PAH) Panel is appropriate when a hereditary cause is suspected for a diagnosis of pulmonary arterial hypertension, such as familial PAH, isolated PAH, pediatric pulmonary hypertension, PAH associated hereditary hemorrhagic telangiectasia (HHT), pulmonary veno-occlusive disease (PVOD).

Ordering & Collection

Specimen Type

Please contact the Genetics laboratory at 206-598-1149 to request a saliva kit (Oragene Dx OCD-100 cheek swabs, OGD-500, or OGD-575 assisted collection). Direct chorionic villi, amniocyte, or amniotic fluid testing requires Genetics Director approval. Please call the lab at 206-598-7021 for approval.

Collection

Acceptable:

  1. Whole blood: 5 mL lavender top (EDTA) tube or yellow (ACD) top tube or 2 mL microtainer lavender top tube.
  2. Extracted DNA from blood, chorionic villi, and amniocytes: 750 ng (concentration >10 ng/uL).
  3. Cultured amniocytes/chorionic villi: MCC is required for testing fetal samples. See Maternal Cell Contamination, Fetal [MCC].
  4. Saliva (collected from Oragene Dx OCD-100 cheek swabs, Oragene Dx OGD-500, or Oragene Dx OGD-575 assisted collection). Please contact the Genetics laboratory at 206-598-1149 to request a kit​.

Unacceptable: Heparin green top tubes
