We report a novel pathogenic variant in SYNJ1 present in homozygosity leading to developmental and epileptic encephalopathy. Currently, there are only 4 reports describing 10 individuals with SYNJ1-related developmental and epileptic encephalopathy. This case expands the clinical knowledge and the allelic heterogeneity associated with SYNJ1 variants.
