KAT6A syndrome is an extremely rare genetic neurodevelopmental disorder in which there is a variation (mutation) in the KAT6A gene. Variations in the KAT6A gene can potentially cause a wide variety of signs and symptoms; how the disorder affects one child can be very different from how it affects another.
