Schematic representation of the analyzed genomic region at 6q22.1q22.31. Genomic coordinates correspond to the hg19 build of the human genome. Red bars represent microdeletions. Dotted vertical lines mark the region of the microdeletion overlap in patients 1, 3, and 4 presenting with seizures. Protein-coding genes, ESTs, and non-protein-coding genes are shown. Black and green color depict opposite directions of transcription. Array CGH log ratio plots of microdeletions in patients 3 and 4 are shown. ASD, autism spectrum disorder; DD, developmental delay; DF, dysmorphic features; FS, febrile seizures; GTCS, generalized tonic-clonic seizures; ID, intellectual disability.
