POU3F1

Chr 1

POU class 3 homeobox 1

Also known as: OCT6, OTF6, SCIP

POU3F1 encodes a transcription factor that binds to specific DNA sequences (octamer motifs) and regulates gene expression, including repression of myelin-specific genes during nervous system development. Mutations cause neurodevelopmental disorders with intellectual disability, often accompanied by ocular abnormalities, and follow an autosomal dominant inheritance pattern. The gene shows moderate constraint against loss-of-function variants (LOEUF 0.705), consistent with its role in essential developmental processes.
