SETD1A and ciliopathy: These variants occur in a number of genes, including SHANK3, DLG3, NALCN, and PACS2 which are critical for synaptic signaling imbalance, CEP120 and BBS5 for ciliopathies, SPTAN1 for spectrins structure, SPATA5, TRAK1, and VPS13B for neuronal organelles trafficking and integrity, TAF6, SMARCB1, DDX3X, MECP2, and SETD1A for gene expression, CDK13 for cell cycle control, ALDH5A1, DPYD, FH, and PDHX for mitochondrial function, and PQBP1, HUWE1, and WDR45 for neuron homeostasis.
