Variant summary
Our verdict is Benign. The variant received -8 ACMG points: 0P and 8B. BP4_StrongBS2
The NM_032776.3(JMJD1C):c.4169C>T(p.Thr1390Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000558 in 1,614,052 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 (★). Synonymous variant affecting the same amino acid position (i.e. T1390T) has been classified as Likely benign.

Early myoclonic encephalopathy Uncertain:1
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. This sequence change replaces threonine with methionine at codon 1390 of the JMJD1C protein (p.Thr1390Met). The threonine residue is weakly conserved and there is a moderate physicochemical difference between threonine and methionine. This variant is present in population databases (rs747375729, ExAC 0.006%). This variant has not been reported in the literature in individuals with JMJD1C-related conditions. ClinVar contains an entry for this variant (Variation ID: 567823). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. -
