Clinical significance

Mutations of the SETD1A gene can cause neurodevelopmental disorder with speech impairment and dysmorphic facies (NEDSID) discovered in 2021, and early-onset epilepsy with or without developmental delay, first described in 2019. According to a review published in 2018, mutations of the SETD1A gene may increase the risk of
