theraSEEK™ Sequence Analysis for Functional Disorders
Next Generation Sequencing test focused on genes associated with metabolism, physiological function, and neurologic development are factors in functional symptoms and disease
Functional disorders encompass a wide range of phenotypes that can present with diverse and multi-system symptomatology. A functional disorder is a medical condition that impairs the normal function of a bodily process, but where the body or associated organs appear normal under examination, imaging, laboratory values, or other standard studies. The occurrence of multiple functional symptoms in one individual suggests a genetic condition as the underlying cause. The theraSEEK™ panel includes a curated selection of genes primarily associated with genetic disorders that present with functional symptoms, and also genes in metabolic and physiologic pathways of interest. In addition to determining a genetic diagnosis, this panel can identify genetic risk factors for multifactorial functional disease.
Genetic testing using Next Generation Sequencing is a valuable tool for obtaining a definitive diagnosis in the patient, thereby providing insight to the prognosis, treatment choices, and recurrence risks for the family. Importantly, understanding the genetic basis of the patient’s condition can assist the clinician in developing a targeted personalized treatment plan, which may include medication, nutritional interventions, supplements, and other therapies or avoidance of certain agents.
theraSEEK™: A selection of 299 genes encompassing:
- Metabolism and physiological functions (amino acids, carbohydrates/glucose, cell signaling, cofactors, metals, select drugs, extracellular matrix, fatty acid oxidation, glycosylation, heme, ion channels, lipids, lysosomes, neurotransmitters, organic acids, peroxisomes, purines/pyrimidines, transcription/translation, urea cycle);
- Metabolic pathways (antioxidant, biopterin, coenzyme Q10, folate, methionine, transsulfuration);
- Neurological development and function;
- Mitochondrial function (electron transport chain, mtDNA replication, morphology).
In addition to full sequencing for rare genetic disease-causing variants, the test includes a SNP analysis for common variants associated with biochemical pathways. Physicians will receive the genetic analysis report, plus a separate SNP analysis report with 60 SNPs, and a data file with over 1,100 SNPs.
Indications for Testing - 2 or more of the following:
| Migraine headache|| Neuropathy/sensory deficits|
|Chronic pain conditions (joint, bone, myalgia)||Autistic spectrum disorder with additional functional symptoms|
|Gastrointestinal conditions (dysmotility, intermittent diarrhea or constipation, abdominal pain, recurrent vomiting, nausea, GERD)||ADHD and other behavioral conditions|
|Fatigue/exercise intolerance||Abnormal movement (tics, tremor, dyskinesia, restless legs)|
|Autonomic dysfunction (dizziness, POTS, arrhythmias)||Sleep disturbance|
|Psychiatric / mood disorders (depression, anxiety, schizophrenia)|
