Whole genome sequencing (WGS) identifies almost all changes in a patient’s DNA by sequencing both the entire protein-coding and the non-coding regions of the genome.
Today there are millions of patients suffering from misdiagnosed or undiagnosed genetic diseases as a result of incomplete genetic testing. Although in certain cases approaches like single gene testing, panel testing, or microarrays can identify the cause of a disease, these analyses are ultimately limited and can fail to reveal the full genetic cause. WGS, in contrast, overcomes such limitations and is the only test that can detect nearly all types of disease-causing genetic variants in one single test.1,2
Most studies on genetic diseases have been heavily biased towards variants in gene coding regions, but this only accounts for approx. 1–2% of a patient’s entire genome. Recently, however, a growing body of studies have demonstrated that clinical WGS offers a more comprehensive analysis than WES and can provide molecular diagnosis where WES can not.1-5 Key pathogenic variants lying outside gene coding regions are growing in number and importance. The spectrum spans from simple sequence variants to complex structural variants.5,6

Features & Performance
|Highly uniform genome and mitochondrial genome coverage|| |
|Advanced detection of nearly all types of variants in one single test||Highly sensitive and specific detection of SNVs, InDels, SVs including CNVs, and mtDNA variants with heteroplasmy ≥15% |
SNVs: single nucleotide variants; InDels: small insertions/deletions; CNVs: copy number variations; SVs: structural variants; mtDNA: variants in mitochondrial DNA;
*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, MPLA; quantitative polymerase chain reaction, qPCR; or chromosomal microarray, CMA)
WGS is recommended especially for the diagnosis of patients with heterogeneous phenotypes, unclear or atypical clinical symptoms, or with a long list of prior differential diagnoses, or who have exhausted other genetic testing options. Recent studies and Medical Genetic Society Statements and Recommendations on clinical WGS support it as a first- or second-line diagnostic test when a patient’s symptoms or family history suggests a genetic cause of the diseases.8-12 This is especially the case when the clinical diagnosis is associated with a high level of genetic heterogeneity and when WGS results in a relevant clinical improvement and/or is a more cost-effective approach. For example, 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.11 We particularly recommend CentoGenome for patients in the following cases:
The symptoms are very broad, complex, or unspecific, not pointing towards specific disease or typical phenotype, as:
- Clinical or genetic heterogeneity (e.g., intellectual disability/developmental delay, epilepsy, muscular dystrophies/muscular disorders, ataxia, neuropathies, cardiomyopathies, skeletal dysplasias, immunodeficiency, deafness, blindness)
- Diseases or patients with atypical clinical presentations or phenotypes (e.g., patient with intracranial aneurysm due to PKD1 gene – polycystic kidney disease)
- Patients with 'blended' clinical presentations and clinical suspicion of dual diagnosis (e.g., patient with deafness and ichthyosis, intellectual disability and severe immunodeficiency)
- Suspicion of a microdeletion or microduplication syndrome (e.g., patients with neurodevelopmental delay, multiple dysmorphisms and/or malformations, growth delay)
- Suspicion of a mitochondrial disorder (e.g., patient with muscular weakness, cardiomyopathy, visual problems)
Prior testing did not provide a conclusive diagnosis, like:
- Patient with autosomal dominant spastic paraplegia, but a negative result for the gene panel
- Patient with neurodevelopmental delay and similarly affected siblings, but a negative testing with microarrays and WES
- Any case where a genetic disorder is suspected but WES is negative
A fast diagnosis is a medical necessity and there is not always the time for serial testing strategies, as seen with:
- Patients severely ill for whom a diagnosis may direct or alter medical management (e.g., children with seizures, hypotonia, neurological abnormalities, and a rapidly deteriorating clinical status)
- Newborns, babies and children where a rapid diagnosis is crucial for prognosis and treatments decisions (e.g., critically ill newborns and children in the neonatal and pediatric intensive care, NICU and PICU)
Our most recent study, where we present the largest cohort of patients with WGS performed in a clinical setting to date, demonstrated the diagnostic strength of CentoGenome as the most comprehensive genetic test and its superiority to WES.5 The results also support that WGS should be considered the 'standard of care' for genetic testing, as well as a first-line stand-alone test for rare disease patients.
CentoGenome helps you tackle challenging and undiagnosed patient cases across all stages of life.
CentoGenome covers a broad spectrum of disorders encompassing >7,000 rare diseases.
Tailored Services to Your Patient's Needs
We offer flexible testing options that allow you to tailor CentoGenome to your patient's needs:
- CentoGenome Prenatal - WGS for ongoing pregnancies with fetal abnormalities
- CentoGenome MOx - multiomic WGS that integrates deep genomic and biochemical insights in a single test
When a rapid diagnosis is a medical necessity
A rapid diagnosis can be critical for timely and appropriate medical intervention. Several recent studies demonstrate how the high diagnostic yield and short turnaround time of WGS enables improved clinical decision making in critically ill newborn infants and children in the Neonatal Intensive Care Units (NICU) or Pediatric Intensive Care Units (PICU).13-17 CentoGenome, with a turnaround time of down to 15 days, acts as a comprehensive and accurate tool that will potentially improve critical decision making when used as a first-line test for diagnosing critically ill newborns or children

CentoGenome includes life-long diagnostic support through (a) proactive, free-of-charge variant reclassification and (b) affordable case-level reanalysis for uncertain or negative results.
Due to the rapid rate of new gene-disease discoveries, it is estimated that 10-20% of uncertain or negative cases can be diagnosed by reclassification and reanalysis.18,19
