SATB2 and cerebellar ataxia: For example, extremely broad (>9 kb in length) H3K4me3 peaks were found at KCNC3, encoding a voltage-gated potassium channel linked to spinocerebellar ataxia, a neurodegenerative condition,50 and at the site of multiple neurodevelopmental risk genes including NMDA glutamate receptor subunit GRIN2B and transcription factor SATB2 (refs 51, 52, 53) (Figure 2d).
