Submissions by phenotype
not specified Uncertain:1
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. -
Early myoclonic encephalopathy Uncertain:1
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). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) 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. -
