Genes affected
JMJD1C (HGNC:12313): (jumonji domain containing 1C) The protein encoded by this gene interacts with thyroid hormone receptors and contains a jumonji domain. It is a candidate histone demethylase and is thought to be a coactivator for key transcription factors. It plays a role in the DNA-damage response pathway by demethylating the mediator of DNA damage checkpoint 1 (MDC1) protein, and is required for the survival of acute myeloid leukemia. Mutations in this gene are associated with Rett syndrome and intellectual disability. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2015]

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 163 of the JMJD1C protein (p.Pro163Leu). This variant is present in population databases (rs766449028, gnomAD 0.006%). This missense change has been observed in individual(s) with a clinical diagnosis of Rett syndrome (PMID: 26181491). ClinVar contains an entry for this variant (Variation ID: 267299). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
