All patients were heterozygous for KDM5B variants; a CADD v1.4 scores range from 1 to 99, with a higher score indicating greater deleteriousness. b Refers to total allele counts and total frequencies in gnomAD dataset v2.1.1. (allele count is the same in the non-neuro subset). “N/A” indicates “non applicable”.
