Wayne W. Grody, M.D., Ph.D.
Dr. Grody is a physician-scientist and nationally recognized leader in medical genetics, molecular diagnostics, and clinical genetic-testing standards. At UCLA, his work has combined patient care, laboratory medicine, genomic testing, research, and medical education. He has also helped develop national quality and ethical guidelines for DNA-based testing.
Background Professor in Pathology and Laboratory Medicine, Pediatrics, and Human Genetics at the UCLA School of Medicine. Director, UCLA Molecular Diagnostic Laboratories and Clinical Genomics Center. Past President of the American College of Medical Genetics. Founding Chair of the VA Advisory Committee on Genomic Medicine. Received lifetime achievement, distinguished service, leadership, teaching, and named lectureship awards from major medical organizations. Served on the NIH–DOE Task Force on Genetic Testing. Helped develop national guidelines for cystic fibrosis and factor V Leiden genetic screening. Contributed to genetic-testing quality and ethical standards for organizations including the FDA, CDC, CAP, ACMG, ASHG, AMP, CLSI, and the Human Genome Project’s ELSI program. Earned his M.D. and Ph.D. from Baylor College of Medicine and completed his residency and fellowship training at UCLA. Board-certified in pathology and medical genetics, with expertise spanning clinical, molecular, and biochemical genetics.
Physician ordered
Clinical testing begins with a qualified ordering clinician.
Clinically interpreted
Results are evaluated with the patient’s phenotype and family history.
Evidence informed. Ethically guided.
Interpretation reflects current scientific evidence and ethical standards in pediatric genetic testing.

SCIENTIFIC ADVISOR
Jeffrey Gulcher, M.D., Ph.D.
Dr. Gulcher is a physician-scientist and pioneer in population genomics, precision medicine, and the genetics of common and complex diseases. He co-founded deCODE Genetics in 1996 and served as Chief Scientific Officer, helping build one of the earliest large-scale platforms linking genomic, genealogical, and longitudinal health data. His work has contributed to major discoveries involving neurological disorders, cardiovascular disease, stroke, type 2 diabetes, and other common diseases.
Background Co-founded deCODE Genetics in 1996. Helped establish deCODE’s population-based approach to discovering genetic risk factors for common and complex diseases. Helped expand population-scale genomic analysis into clinical diagnostics, rare-disease interpretation, cancer genomics, and international precision-medicine programs. Contributed to landmark discoveries including PITX2 and ZFHX3 in atrial fibrillation, TCF7L2 in type 2 diabetes, and 9p21 in myocardial infarction, among others. Contributed to the development of reporting standards for genetic risk-prediction studies. Has authored or co-authored more than 200 peer-reviewed scientific publications. Earned his M.D. and Ph.D. from the University of Chicago. Completed his neurology residency through the Harvard Longwood Neurology Training Program at Brigham and Women’s Hospital and Beth Israel Deaconess Medical Center.

SCIENTIFIC ADVISOR
Nicholas Katsanis, Ph.D.
Dr. Nicholas Katsanis is an internationally recognized scientist known for advancing the understanding of ciliopathies, autism, and other rare and complex genetic disorders. He has also advanced the concept that genetic findings exist along a continuum and must be interpreted within the patient’s broader genetic and clinical context.
He is a Simons Foundation Autism Research Initiative (SFARI) Investigator and a member of its Scientific Review Board. His research has examined how autism-associated genetic changes, including the 16p11.2 copy-number variant, affect neurodevelopment.
Background Vice President of Research, New York Biohub at Chan Zuckerberg Initiative Founding Director of the Center for Human Disease Modeling at Duke University Former faculty member at Duke University, Johns Hopkins University, and Baylor College of Medicine He is a former SFARI Investigator and member of the SFARI Scientific Review Board Led research into genes underlying autism-associated 16p11.2 copy-number changes Led interdisciplinary teams and international collaborations in genome interpretation, disease modeling, and therapeutic development Published more than 350 scientific papers and holds 11 patents.

GENETIC COUNSELING ADVISOR
Maggie Law, CGC, FHGSA., MMedSc., MGenCouns
Dual U.S. and Australia Board-Certified Genetic Counselor
Ms. Law is dual-certified in genetic counseling in the United States and Australia. She has extensive experience counseling patients and families and interpreting complex genetic findings, with particular expertise in underrepresented populations.
Background Has more than ten years of experience in variant analysis, clinical interpretation and genetic counseling. Works with individuals and families from diverse ethnic, cultural, and linguistic backgrounds. Specializes in interpreting complex or uncertain genetic findings in underrepresented populations, with multilingual, and culturally sensitive summaries. Translates complex findings, including uncertain variants, inherited cancer risks, carrier findings, and polygenic risk scores, into understandable information. Supports the accurate, responsible, and ethical use of genomic interpretation and communication.
Clear, clinically meaningful genetic answers should be within every family’s reach
Parents want to understand genetic causes of conditions affecting their children, so they can make informed decisions, improve treatment, and achieve better outcomes.
But too few have access to reliable, clinically meaningful genomic testing, clear and simple reports, follow-up care from trusted health professionals, and without delays from insurance approval, all at a cost that feels truly within reach. We’re here to change that.
Our team has spent over a decade helping doctors and families gain access to credible genetic testing. We focus on offering genetic tests that are affordable, delivering results in a clear and meaningful way, and supporting families in using the information to take better care of their children and plan for the future.
