SLC4A10 and microcephaly: Neuroradiological features of the SLC4A10-related neurodevelopmental disorder included microcephaly, with a relative preservation of brain volume compared to OFC and narrow, sometimes slit-like lateral ventricles similar to those seen in the Slc4a10−/− mouse model (Supplementary Fig. 4), even in those cases with less well preserved cerebral volume.
