KIF1A Day is observed worldwide every April 28 to promote awareness of KIF1A-associated neurological disorder (KAND), a rare genetic condition caused by mutations in the KIF1A gene. This gene is crucial for producing the KIF1A protein, which transports essential molecules within neurons. Symptoms of KAND can vary significantly among individuals and may include hypotonia, ataxia, seizures, and developmental delays, among others. As of 2025, KAND has been diagnosed in about 500 people globally, often leading to misdiagnosis due to symptom overlap with more common disorders. The day was established by KIF1A.ORG, a foundation dedicated to supporting affected patients and advancing research for a cure. Activities on this day include educating others about the disorder, donating to KIF1A.ORG, and sharing information on social media using the hashtag #KIF1ADay.
