Labcorp Genetics (formerly Invitae), Labcorp RCV001207030 SCV001378367 uncertain significance Early myoclonic encephalopathy 2019-07-20 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals with JMJD1C-related conditions. 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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant is not present in population databases (ExAC no frequency). This sequence change replaces lysine with glutamic acid at codon 252 of the JMJD1C protein (p.Lys252Glu). The lysine residue is moderately conserved and there is a small physicochemical difference between lysine and glutamic acid.
