Thanks, Sabrina, and thank you all for joining us. 2023 was a pivotal year for us at GeneDx. We're on a stronger path forward and closer to our goal of reaching profitability in 2025. Last year, we centered our entire team on three goals: one, increasing utilization of our industry-leading exome and genome; two, improving our average reimbursement rate; and three, dramatically reducing our cash burn. The combination of these three organizational goals ultimately ensures that our teams were focused on what's clinically best for patients and what's best for the financial health of the company. And that focus paid off. Our teams worked with deep commitment in the fourth quarter and delivered $58 million of revenue, driven by more than 68% year-over-year growth in exome and genome test revenue, expanded our adjusted gross margins to 56% and ended the year ahead of our expected cash position, demonstrating a 51% year-over-year reduction in burn. We're proud of our team's performance, and we're prepared to rinse and repeat that same level of commercial and operational execution. As we look to 2024 and based on what we're seeing so far, you can continue to expect this level of focus on exome and genome revenue growth, gross margin expansion and disciplined cash management. The investments that we're making, whether it's in commercial, operations, medical affairs, our product and technology are directly tied to these goals. In the fourth quarter, we realigned our sales strategy to focus on account profitability. We have right-sized our sales territories and further refined our commercial tactics and tools with account profitability in mind, and we're seeing good progress. Our strategy continues to include efforts that drive exome conversion with current customers, but we're taking a more precise yet high impact approach with new customer acquisition, mainly targeting pediatric neurologists. We continue to see better traction and faster growth ramps with these new ordering providers compared to lower productivity accounts, including general pediatrics. We're also keeping our operations team focused on the biggest levers for our P&L. Reports out, billing operations and COGS reduction, among other efforts to ensure we maintain our turnaround time. Our product and tech team is working on our strategy to further scale our operations, improve our customer experience, open up access with the EMR integrations, automate our billing operations and drive greater efficiency in every aspect of the business. The total addressable market in pediatrics is large, and while we are the dominant provider of whole-exome sequencing today, we've only penetrated about 3% of the total addressable market of $3 billion in the US-only pediatric setting. It's a market that we're developing in pediatric neurology where clinical evidence and health economics strongly support the transition to exome analysis. We will also expand further into the general pediatric setting over the coming years as guidelines and payer policy continue to evolve to become more ready for commercial expansion and execution. On the other side of that is an entire $10 billion market in the US only for adult conditions that we'll be working to develop over the mid and long-term, and along the way, there's a growing data opportunity in rare disease drug development. We've steadily added biopharma partners and have 20 active programs, mainly with biotech companies who are relying on us to find patients with a specific variant for clinical trial purposes. We're expecting that business to continue to grow at a similar pace. We think there's great promise in the role that diagnostics can plan rare disease drug development. In fact, the New York Times recently highlighted a new gene therapy for children with hearing loss. They featured an 11-year-old boy who had no ability to hear until researchers at the Children's Hospital of Philadelphia gave him an experimental gene therapy from our partner, Akouos and Eli Lilly Company. The boy was able to hear sound for the first time ever and now the company is expanding its research to several other centers. And just a few weeks ago, FDA Commissioner, Dr. Robert Califf said the agency will need to get creative about regulatory pathways, given the tsunami of rare disease and gene therapies that the FDA is anticipating. Rare disease treatments are reliant upon rare disease diagnosis, and that's what we do best at GeneDx. We believe this market is developing and are well-positioned to be the genetic testing partner of choice for these companies. Looking forward to 2024 guidance, we expect a similar growth trajectory as demonstrated quarter-over-quarter in 2023 as we continue to focus the teams on driving exome and genome utilization and improving our reimbursement rate. With that in mind, we expect to deliver between $220 million to $230 million in revenue this year, and Kevin will provide some additional commentary. With a growing proportion of our test mix shifting to exome, we will continue to unlock greater gross margins, effectively converting more of the market to better volumes, and with the continued decrease in cash burn, we will end the year with strong operating leverage to put us on the precedence of profitability heading into 2025. And with that, I'll hand the call over to Kevin.
