The following sections explore the various facets of the Baylor Genetics test menu, highlighting test types, clinical applications, and unique features that set this laboratory apart.
Comprehensive Gene Panels
Gene panels at Baylor Genetics are designed to analyze multiple genes simultaneously, making them particularly useful for conditions with genetic heterogeneity. These panels are expertly curated to include genes with well-established clinical relevance, ensuring thorough evaluation of suspected inherited disorders.
Each panel targets a specific clinical indication, such as neurological disorders, cardiomyopathies, or metabolic syndromes. The panels typically range from a handful to over a hundred genes, balancing breadth with clinical utility.
Baylor Genetics also offers customizable panels, allowing providers to tailor testing to their patient’s unique presentation.
Utilizing next-generation sequencing (NGS) technology, these panels provide high sensitivity and specificity. This means that clinicians receive comprehensive results faster, aiding in timely diagnosis and management.
Popular Gene Panels and Applications
- Neurology Panels: Including epilepsy, intellectual disability, and neurodegenerative disease panels.
- Cardiology Panels: Covering inherited arrhythmias, cardiomyopathies, and sudden cardiac death syndromes.
- Oncology Panels: Focused on hereditary cancer syndromes such as BRCA1/2 and Lynch syndrome.
- Metabolic Panels: Targeting inborn errors of metabolism and mitochondrial disorders.
“The strategic design of gene panels allows for a focused yet comprehensive approach, increasing diagnostic yield while reducing unnecessary testing.” – Baylor Genetics Scientific Director
Single Gene and Targeted Testing
For cases where clinical features strongly suggest a specific genetic condition, Baylor Genetics offers single gene and targeted mutation testing. This approach is often more cost-effective and faster when the mutation spectrum is well understood.
Single gene testing can confirm or rule out a diagnosis with high confidence and is particularly useful for diseases with a classic presentation or well-established genotype-phenotype correlations. Targeted mutation analysis is often used for known familial variants, enabling rapid carrier testing or prenatal diagnosis.
The laboratory utilizes robust methodologies such as Sanger sequencing and allele-specific PCR to ensure high accuracy. This testing approach is also integrated into broader diagnostic workflows where initial panel testing may be followed by single gene analysis for confirmation.
Typical Scenarios for Single Gene Testing
- Cystic Fibrosis: Testing for common CFTR mutations in patients with characteristic symptoms.
- Huntington’s Disease: Detection of CAG repeat expansions in the HTT gene.
- Familial Hypercholesterolemia: LDLR gene mutation analysis to guide treatment.
- Carrier Testing: Targeted mutation analysis for known familial variants.
“Targeted testing remains a vital tool when clinical suspicion is high, streamlining diagnosis and enabling focused counseling.” – Clinical Geneticist at Baylor Genetics
Exome and Genome Sequencing Services
For patients with complex or undiagnosed conditions, Baylor Genetics offers both whole exome sequencing (WES) and whole genome sequencing (WGS). These comprehensive tests analyze thousands to millions of genetic variants across the coding and non-coding regions of the genome.
Exome sequencing focuses on the protein-coding regions, which represent about 1-2% of the genome but harbor the majority of known disease-causing mutations. Genome sequencing extends beyond the exome to include regulatory regions, structural variants, and other difficult-to-detect changes.
Both approaches utilize advanced bioinformatics pipelines to filter and interpret variants, prioritizing those most likely to be clinically relevant. Baylor Genetics also provides phenotype-driven analysis, integrating clinical data to enhance diagnostic accuracy.
Comparing Exome and Genome Testing
| Feature | Exome Sequencing | Genome Sequencing |
| Coverage | Protein-coding regions (~20,000 genes) | Entire genome, including non-coding regions |
| Turnaround Time | 4-8 weeks | 6-10 weeks |
| Variant Types Detected | SNVs, small indels | SNVs, indels, structural variants, CNVs |
| Cost | Lower | Higher |
“WES and WGS have transformed the diagnostic landscape for rare diseases, offering hope where traditional methods fall short.” – Baylor Genetics Genomics Team
Biochemical and Metabolic Testing
Baylor Genetics complements its molecular testing offerings with a suite of biochemical and metabolic assays. These tests measure enzyme activities, metabolite levels, and other biochemical markers that can indicate inherited metabolic disorders.
Biochemical testing remains critical in newborn screening, diagnosis of metabolic diseases, and monitoring therapeutic interventions. Baylor’s laboratory provides high-sensitivity assays that support rapid and accurate clinical decision-making.
Incorporating biochemical results alongside genetic data enhances diagnostic confidence, especially in disorders where genetic variants alone may not fully explain the clinical phenotype.
Common Biochemical Tests
- Enzyme Assays: Such as acid alpha-glucosidase for Pompe disease.
- Metabolite Profiling: Including amino acids, organic acids, and acylcarnitines.
- Lysosomal Storage Disorder Panels: Combining enzymatic and molecular analyses.
- Newborn Screening Confirmation: Follow-up testing to confirm screening results.
“Biochemical testing bridges the gap between genotype and phenotype, providing crucial functional insights.” – Baylor Genetics Metabolic Specialist
Carrier Screening Options
Carrier screening is essential for identifying individuals at risk of passing genetic conditions to their offspring. Baylor Genetics offers extensive carrier screening panels that cover a broad range of recessive and X-linked disorders.
The panels are designed to be inclusive of diverse populations, recognizing the importance of ethnic and geographic variability in carrier frequencies. Providers can choose from pre-designed panels or customize based on patient ancestry and family history.
Results include comprehensive variant interpretation and risk assessment, equipping couples with the information needed to make informed reproductive decisions.
Features of Baylor Carrier Screening
- Expanded Panels: Screening for over 200 conditions including cystic fibrosis, Tay-Sachs, and spinal muscular atrophy.
- Population-Specific Options: Tailored panels for Ashkenazi Jewish, African American, and other groups.
- Reflex Testing: Additional follow-up testing if variants of uncertain significance are detected.
- Comprehensive Reporting: Clear explanations of carrier status and next steps.
“Proactive carrier screening empowers families and helps reduce the incidence of inherited disorders.” – Genetic Counselor at Baylor Genetics
Pharmacogenomics Testing
Pharmacogenomics (PGx) testing at Baylor Genetics helps personalize medication choices based on an individual’s genetic makeup. By identifying variants that affect drug metabolism, efficacy, and toxicity risk, these tests enable safer and more effective treatment plans.
Baylor Genetics offers PGx panels that analyze genes involved in drug response pathways, covering a variety of medication classes such as anticoagulants, antidepressants, and oncology drugs. The results help clinicians optimize dosing and avoid adverse drug reactions.
Integration of PGx data into electronic health records allows for seamless clinical application and ongoing patient management.
Key Pharmacogenomics Genes Tested
- CYP2C9 and VKORC1: Influencing warfarin dosing.
- CYP2D6: Affecting metabolism of antidepressants and opioids.
- TPMT: Relevant for thiopurine drugs in leukemia treatment.
- SLCO1B1: Associated with statin-induced myopathy risk.
“Pharmacogenomics testing is a crucial step toward precision medicine, reducing trial-and-error in prescribing.” – Baylor Genetics PGx Specialist
Interpretation and Reporting Excellence
Baylor Genetics distinguishes itself not only through its broad test menu but also through high-quality interpretation and reporting services. Each test result is carefully analyzed by expert geneticists and molecular pathologists to ensure clinical relevance and clarity.
Reports provide detailed variant classification following ACMG guidelines, clinical correlations, and recommendations for further testing or management. This level of detail supports informed decision-making by healthcare providers and facilitates patient counseling.
Additionally, Baylor Genetics offers post-test consultation services, allowing providers to discuss complex cases directly with specialists. This collaborative approach enhances understanding and application of genetic information.
