Thank you for your dedication to finding answers for your patients.
When diagnoses are unclear, Whole Genome Sequencing (WGS) may provide answers to guide patient care and outcomes. Whether you’re coordinating testing, obtaining consent, or reviewing results, we hope these resources help streamline the process.

When to Consider rWGS
rWGS may be appropriate for:
- No unifying diagnosis
- Intractable seizures
- Neonatal hypotonia
- Metabolic disturbances (e.g., hyperammonemia, profound hypoglycemia)
- Unexplained cardiac arrest
- Congenital cardiomyopathy
- Respiratory insufficiency at term
- Other unexplained congenital anomalies
- When a 5-day TAT for full written report is needed
When to Consider WGS
For persistent, unexplained findings:
- Developmental delay or intellectual disability
- Recurrent seizures without a known etiology
- Failure to thrive with suspected syndromic features
- Persistent hypotonia or movement abnormalities
- Congenital anomalies with no diagnosis
- Strong suspicion of a genetic disorder despite nondiagnostic panel testing
- Positive family history of a suspected genetic condition
- When a 21-day TAT is acceptable
Support for You & Your Patients
Our approach integrates multimodal data, AI-enhanced expert interpretation, and dedicated end-to-end support to inform your clinical care.

Detect variants across 20,000 genes to help explain a patient’s symptoms and a potential diagnosis by looking at multiple variant types.

RNASeq tailors the analysis of qualified* variants specific to the patient, contributing to a reduction in the number of variants of uncertain significance (VUS) and an increase in diagnostic yield.
*Meets our prediction algorithm criteria.

Our mitochondrial DNA sequencing provides enhanced sensitivity by detecting heteroplasmic variants present at levels as low as 5%. The increased resolution improves the clinical utility of testing and enhances diagnostic confidence.

Global MAPS®* (Metabolomic Assisted Pathway Screen), analyzes hundreds of metabolites to identify changes or irregularities in biochemical pathways not currently detected by routine clinical or genetic testing.

We use supplemental testing methods to assess 29 high impact STR disorders.

The support of comparator genomes from the parents (duo/trio) may help explain the patient’s condition. Requires comparator samples from either or both parents – only available with duo and trio WGS formats.

Our proprietary analysis pipeline is integrated with an industry leading AI solution to accelerate candidate gene variant prioritization – leveraging globally esteemed databases and curated clinical literature to reveal and support the underlying cause.

Baylor Genetics offers patient and provider support that extends beyond testing. Our services include assistance with insurance and financial options, access to genetic counseling after certain results, physician-initiated reanalysis as knowledge evolves, and help coordinating phlebotomy services. We also provide multiple testing formats, including Duo, Trio, Quad, and rapid testing to help identify the genetic basis of rare disease.
Our WGS assay is PCR-free, run at 40x genome-wide coverage, and is aligned to the GRCh38 reference genome and includes:
- Detects SNVs, indels, CNVs, STRs, and mitochondrial genome variants in exonic, intronic, and noncoding regions
- Includes UPD analysis (when both parents are tested as part of trios and quads)
- Reporting of findings in genes with no known disease association (when both parents are tested as part of trios and quads) Companion testing for BG WGS:
- Global MAPS® metabolomic profiling (test code 4900/4901)
- WGS reanalysis (test code 1897)
Optional:
- RNA sequencing for reclassification of eligible variants
- Reporting of ACMG Secondary Findings (each member of the family can individually be opted in)
- Reporting of other Incidental Findings not associated with the patient’s phenotype but that might impact their medical management

Secondary and Incidental Findings
Medically actionable variants that might not be associated with a patient’s current disease still might provide important information for their medical management in the future. Baylor Genetics provides the option for the reporting of pathogenic and likely pathogenic variants in genes on the ACMG Secondary Findings list. In addition, other incidental findings unrelated to the patient’s phenotype but that might impact their medical management can be separately opted into. (Must Opt-in)
CAP Accredited and CLIA Certified
The tests described have been developed and their performance characteristics determined by the CLIA-certified laboratory performing the test. The tests have not been cleared or approved by the US Food and Drug Administration (FDA). CAP accredited, and CLIA certified.
It is important to understand that genetic tests, even if negative, cannot rule out every variant. Genetic testing, while highly accurate, might not detect a variant present in the gene(s) tested. This can be due to limitations of the information available about the gene(s) being tested, or limitations of the testing technology. It is not possible to exclude risks for all genetic diseases for you/your child and your family members. It is possible that even if the test identifies the underlying genetic cause for the disease in your family, this information may not help in predicting the progression of disease or change management or treatment of disease.
