Relevance to Autism
De novo loss-of-function (LoF) variants in the KATNAL2 gene were identified in autistic probands from simplex families in two separate reports (PMIDs 22495306 and 22495309). Analysis of rare coding variation in 3,871 ASD cases and 9,937 ancestry-matched or paternal controls from the Autism Sequencing Consortium (ASC) in De Rubeis et al., 2014 identified KATNAL2 as a gene meeting high statistical significance with a FDR 0.01, meaning that this gene had a 99% chance of being a true autism gene (PMID 25363760). A third de novo loss-of-function variant and a likely damaging de novo missense variant in KATNAL2 were identified in probands from the Autism Genetic Resource Exchange (AGRE) in Stessman et al., 2017 (PMID 28191889).
