Green List (high evidence)

Reported in ID cohort (with Rett-like phenotypic overlap) with supporting functional studies (PMID: 26181491). 7 individuals with rare variants identified, and variants demonstrated to be de novo in 2, one with a Rett-like phenotype and the other with ID. Functional study of the JMJD1C mutant Rett syndrome patient demonstrated that the altered protein had abnormal subcellular localization, diminished activity to demethylate the DNA damage-response protein MDC1, and reduced binding to MECP2. JMJD1C protein shown to be widely expressed in brain regions and that its depletion compromised dendritic activity.

Splice-disrupting JMJD1C variant reported in association with learning disability and myoclonic epilepsy (PMID 32996679).

Disruption of gene due to balanced translocation (PMID 33591602) implicated in autism spectrum disease phenotype.
