Unlocking MDR1 Mutations in Cats: Prevalence, Perils, & Protocols

Join us for an evidence-based update on the feline multidrug sensitivity gene (MDR1 gene, also known as ABCB1 gene). Dr. Jeba Chelladurai will discuss the feline ABCB1 1930_1931del TC variant, a key loss-of-function mutation that can cause neurotoxicity following exposure to certain antiparasitic and other commonly used drugs. Dr. Chelladurai will review the MDR1 essentials, including how this 2-base pair deletion may place cats carrying 2 copies of the variant at high risk, and share new data from the largest screening study to date of 12,000 US domestic cats. Actionable takeaways will include how to identify which feline patients warrant genotyping and how to approach prescribing decisions with confidence.
