Interestingly, mutations in all four genes (KDM5C, ARX, ZNF711 and PHF8) are associated with X-linked NDDs comprising intellectual disability as a core feature. in vitro analysis of the KDM5C promoter revealed that ARX and ZNF711 function as antagonist transcription factors that activate KDM5C expression and compete for the recruitment of PHF8.
Loss-of-function mutations in the histone demethylases KDM5A, KDM5B, or KDM5C are found in intellectual disability (ID) and autism spectrum disorders (ASD) patients.
Mutations in <i>KDM5C</i> cause Mental Retardation, X-linked, Syndromic, Claes-Jensen type (MRXSCJ, OMIM #300534) and are one of the most common causes of X-linked ID.
We investigated a family of three boys with intellectual disability, and among them we identified two different mutations in KDM5C, located at Xp11.22, using whole-exome sequencing.

Here, we report on a female patient with severe ID and autistic features carrying a de novo 0.4 Mb deletion containing six coding genes including KDM5C and IQSEC2.
To access the impact of KDM5C variants on XLID, a cohort of 143 males with a family history of intellectual disability (ID) suggestive of X-linked inheritance were enrolled.
In this study, we describe clinical and genetic findings of a Brazilian family co-segregating a novel nonsense mutation (c.2172C>A) in exon 15 of KDM5C gene with the intellectual disability phenotype.
Intriguingly, mutations within the genes encoding the H3K9-specific methyltransferase, EHMT1, and the H3K4-specific histone demethylase, JARID1C/SMCX, have been linked to mental retardation and autism, respectively.
Mutation analysis of the JARID1C gene was conducted in the following cohorts: probands from 23 XLMR families linked to Xp11.2, 92 males with mental retardation and short stature, and 172 probands from small XLMR families with no linkage information.
