GENETIC TESTING SOLUTIONS FOR: NEUROLOGY, NEUROMUSCULAR, AND CARDIOLOGY DISORDERS

EGL has nearly 50 years of genetic testing history built upon a strong academic foundation. Our expertise spans common and rare genetic disease testing, genomic variant interpretation, test development and research. As we have grown, we have evolved into a high-science and high-performing CLIA-certifi ed and CAP-accredited laboratory with over 1,100 test offerings across biochemical genetics, cytogenetics, and molecular genetic testing.

COMPREHENSIVE OFFERINGS There are signifi cant genetic and phenotypic heterogeneity for disorders involving neurology, neuromuscular, and cardiovascular systems, and obtaining a specifi c diagnosis is important for prognosis, patient management, and development of therapeutic strategies. Consider this collection of test offerings for patients with heart disease, , autism spectrum disorders, movement disorders, epilepsy, and more. Identifi cation of a causative genetic defect may provide information for prognosis and therapeutic intervention, and is required for carrier testing and early prenatal diagnosis.

TEST OFFERINGS FOR THE FOLLOWING CLINICAL INDICATIONS: • Cardiomyopathy and cardiovascular diseases • Autism and intellectual disabilities • Neuromuscular disorders and muscular dystrophy • Epilepsy • Movement disorders ADVANTAGES OF PARTNERING WITH EGL GENETICS: • Board-certifi ed laboratory directors & genetic counselors to answer clinical and analytical questions • Multiple sample collection options for DNA-based tests. Contact us to determine which collection option is best for your patient • Customizable NGS panels with add-on genes available upon request for no additional charge • Commitment to accurate sequence variant classifi cation: Free targeted parental testing for up to two variants of unknown signifi cance following proband only testing, plus complementary periodic variant review and report updates, variant database publicly available, and open data sharing via ClinVar • Competitive turnaround times for all testing with expedited testing when clinically indicated • Client portal for convenient result delivery • Billing experts & insurance specialists available to assist with pricing, payments, insurance coverage, prior-authorizations, and more
