Whole Exome Sequencing – Getchecked Clinic
It takes approx. 7 years to diagnose a patient with a rare disease. With Getchecked Whole Exome Sequencing, we can turn those years into days – powered by our best-in-class insights based on superior technology, our extensive clinical experience, and wealth of genetic data in rare diseases.
Getchecked’s Enhanced Whole Exome Sequencing Service
Overcoming the Obstacles of Rare Disease Diagnostics with Getchecked Clinic
With more than 7,000 identified rare diseases and approximately 80% being linked to genetic causes, diagnosing rare disease patients can often be difficult – resulting in lengthy, expensive, and emotional diagnostic odysseys.1,2
With WES, this doesn’t have to be the case. Containing the majority (~85%) of known disease-causing changes, WES uncovers the cause of rare diseases in less time and at a lower overall cost – leading to better patient outcomes. With Getchecked Clinic, we’ve taken WES to the next level. Enhanced to provide unparallel clinical coverage and diagnostic power in a single test, our product design and medical interpretation utilizes the world’s largest rare disease-centric Bio/Databank containing >31 million unique variants from over 120 countries.
The Results: Diagnosing complex and unsolved patient cases – quicker and with the highest levels of certainty.

Coupling insights from our extensive and unique rare disease-centric Bio/Databank with superior omics technology, patients and physicians benefit from a unique approach that increases diagnostic yield by up to 20% compared to routine WES3-12 via enhanced coverage of the exome, full mitochondrial genome, and known clinically-associated genes and variants.
Features & Performance
- Mean depth ≥100 x
- Highly uniform coverage of the entire exome (~20,000 genes), +/- 10 bp exon-intron boundaries, and complete mitochondrial genome (37 genes); with ≥ 98.0% target regions covered at ≥20 x
- 8,000 disease-associated genes (OMIM®, HGMD®, Getchecked Clinic's rare disease-centric Bio/Databank), with ≥99.0% target regions covered at ≥20 x
- >99.0% of all known clinically relevant variants in coding and non-coding regions (HGMD®, ClinVar, Getchecked Clinic's rare disease-centric Bio/Databank)
- Highly sensitive and specific detection of SNVs, InDels, CNVs of exon-level to cytogenomic-level changes, UPD*, and mtDNA variants with heteroplasmy ≥15%
-
Sensitivity
SNVs and InDels (≤55 bp) >99.6%
CNVs (≥3 exons)** >95.0% - Specificity of >99.9% is guaranteed for all reported variants**
SNVs: single nucleotide variants; InDels: small insertions/deletions; CNVs: copy number variations; UPD: uniparental disomy; mtDNA: mitochondrial DNA
*UPD screening is performed using an in-house specific algorithm for the following well-known clinically relevant chromosomal regions: 6q24, 7, 11p15.5, 14q32, 15q11q13, 20q13 and 20
**CNV detection software has a sensitivity >95.0% for all homozygous/hemizygous and mitochondrial deletions, as well as heterozygous deletions/duplications and homozygous/hemizygous duplications spanning at least three consecutive exons
***Variants with low quality and/or unclear zygosity are confirmed by orthogonal methods (i.e., SNVs and InDels by Sanger sequencing; CNVs by Multiplex ligation-dependent probe amplification, MLPA; quantitative polymerase chain reaction, qPCR; or chromosomal microarray, CMA)
When Is WES Recommended?
We recommend WES for complex and undiagnosed cases with suspicion of genetic causes.
WES is conventionally recommended when patients present complex, heterogeneous phenotypes that are suggestive of multiple conditions or are otherwise unclear or atypical. WES may also be recommended when a prior genetic test was unsuccessful. The latest clinical evidence also supports WES as a first-line test when a patient’s symptoms or family history suggests a genetic cause of the diseases. This is especially true for neurodevelopmental disorders, including intellectual disability, global developmental delay, and autism spectrum disorder due to the high diagnostic yield.10, 13 The ACMG (American College of Medical Genetics and Genomics) recommends the use of exome/genome sequencing as first-tier test for children with intellectual disability, developmental delay, or multiple congenital anomalies.14 The test results from WES may also lead to more rapid diagnoses, improved prevention of symptomatic illness, more targeted treatments or even end the need for some costly or invasive procedures.10, 14–17
We particularly recommend Getchecked Clinic's for patients when:
- Symptoms are very broad, complex, or unspecific, not pointing towards specific disease or typical phenotype e.g., patients with developmental delay, intellectual disability, autism spectrum disorder, epilepsy
- Suspicion of chromosomal imbalances, microdeletion, or microduplication syndromes e.g., children with global development delay, and/or multiple congenital anomalies, DiGeorge syndrome
- Clinical suspicion of mitochondrial disease e.g., patients with muscular weakness, cardiomyopathy, visual problems
- A severe presentation in the neonatal or childhood period e.g., neonate babies and infants critically ill in Neonatal and Pediatric Intensive Care Units (NICU and PICU, respectively)
- Prior genetic testing did not provide a conclusive diagnosis e.g., patient with neurodevelopmental delay, with similarly affected siblings, and negative testing with microarrays
- Need a cost-conscious alternative to Whole Genome Sequencing (WGS)
GetcheckedXome can help you tackle challenging and undiagnosed patient cases across all stages of life and covers a broad spectrum of disorders encompassing >7,000 rare diseases
Tailored Services Paired With Life-Long Support
We offer flexible testing options and additional services to provide a Getchecked Clinic’s analysis tailored to patients’ needs, including WES for ongoing pregnancies with fetal abnormalities for prenatal diagnostics (Getchecked Clinic Prenatal). Additionally, we offer an advanced multiomic WES solution, Getchecked Clinic MOx, which integrates deep exomic and biochemical insights in a single test to enable early diagnosis, better prognosis, and optimized treatment planning.
Committed to improving the lives of patients with rare diseases, GetcheckedXome is paired with life-long diagnostic support via a free-of-charge and proactive reclassification program, as well as an affordable case-level reanalysis in case of uncertain or negative results. WES diagnostic yield is continuously increasing due to the rapid rate of new gene-disease discoveries, and it is estimated that about 10–20% of undiagnosed patients can be diagnosed by reclassification and genomic data reanalysis.15, 18
