Breakthrough Genomics, Breakthrough Genomics RCV004596711 SCV005088904 pathogenic Developmental and epileptic encephalopathy, 2 2021-05-30 criteria provided, single submitter clinical testing This variant is predicted to cause a frameshift and consequent premature termination of the protein (p.Thr472AsnfsTer6) and the resultant protein will likely to lack the C-terminus domain of the protein [PMID: 31450582]; this will likely result in loss-of-function. Due to the introduction of a premature stop codon, this aberrant transcript will likely be targeted by the nonsense-mediated mRNA decay (NMD) mechanism [PMID: 15040442]. The variant seems to be a novel variant, as it has not been previously reported in population databases or in the literature. However, several other truncating variants lying downstream of the identified variant, have been previously reported as ‘pathogenic’ in the ClinVar database context of early infantile epileptic encephalopathy 2 and epileptic encephalopathy.
