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]

The c.1900C>T (p.H634Y) alteration is located in exon 8 (coding exon 8) of the JMJD1C gene. This alteration results from a C to T substitution at nucleotide position 1900, causing the histidine (H) at amino acid position 634 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces histidine, which is basic and polar, with tyrosine, which is neutral and polar, at codon 634 of the JMJD1C protein (p.His634Tyr). This variant is present in population databases (rs368298748, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with JMJD1C-related conditions. ClinVar contains an entry for this variant (Variation ID: 529713). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt JMJD1C protein function with a negative predictive value of 80%. 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. -
