With years of published research<sup>1<\/sup> and collaborations with leading technology partners, GeneDx is uniquely positioned to bring long-read sequencing into clinical practice, combining advanced sequencing of genomic data, rich phenotypic data, and deep clinical expertise to deliver meaningful answers for patients.<\/p>\n<p>\nLeveraging insights from GeneDx Infinity\u2122 and decades of clinical interpretation, GeneDx will identify where long-read sequencing can deliver the greatest diagnostic value and offer lrWGS upfront for eligible patients. This targeted, phenotype-driven approach aims to reduce sequential testing, close diagnostic gaps and accelerate diagnosis.<\/p>\n<p>\n\u201cLong-read sequencing is providing us with substantially more powerful insights into the human genome than previously possible. We are especially interested in how this technology helps us to understand the cause of a patient\u2019s rare disease when their genome is from a population that has been under-studied,\u201d said John Greally, D.Med., Ph.D., chief of genomics, and professor of genetics and pediatrics at Albert Einstein College of Medicine, clinical geneticist at the Children&#8217;s Hospital at Montefiore (CHAM), and co-director of the NY Center for Rare Diseases at Montefiore. \u201cThe future for rare disease diagnostics combines long-read sequencing with enhanced clinical information describing the patient, adding the expertise of clinicians to the solution, finally providing answers for patients and families living with these conditions.\u201d<\/p>\n<p>\n\u201cEvery advancement in genomic medicine should bring patients closer to answers,\u201d said Linda Genen, MD, MPH, Chief Medical Officer, GeneDx. \u201cLong-read sequencing creates new opportunities to uncover complex genetic variation, but the true value lies in how those findings are interpreted and applied. By combining advanced sequencing with our deep genomic data and clinical expertise, we aim to equip clinicians with clearer insights to navigate complex cases, make more informed diagnostic decisions and get patients closer to answers.\u201d<\/p>\n<p>\nThe early access program will be available by year-end and is part of GeneDx&#8217;s continued focus on genome innovation to expand diagnostic capabilities and deliver more answers to more patients.
