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]

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. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. ClinVar contains an entry for this variant (Variation ID: 1025639). This variant has not been reported in the literature in individuals affected with JMJD1C-related conditions. This variant is present in population databases (rs76935733, gnomAD 0.0009%). This sequence change falls in intron 18 of the JMJD1C gene. It does not directly change the encoded amino acid sequence of the JMJD1C protein. It affects a nucleotide within the consensus splice site. -
