Variant summary
Our verdict is Likely benign. The variant received -6 ACMG points: 0P and 6B. BP4_ModerateBS2
The NM_032776.3(JMJD1C):c.238A>T(p.Thr80Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000359 in 1,613,762 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. T80A) has been classified as Uncertain significance.

Early myoclonic encephalopathy Uncertain:1
This sequence change replaces threonine, which is neutral and polar, with serine, which is neutral and polar, at codon 80 of the JMJD1C protein (p.Thr80Ser). This variant is present in population databases (rs377459705, gnomAD 0.006%). 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: 839143). 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 tolerated. 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. -
