Inactivating mutations in the metal transporter gene SLC39A8, which codes for the transporter protein ZIP8, result in intellectual disability, cranial malformations, cerebellar atrophy, hypotonia, low blood manganese, and impaired glycosylation (Boycott et al., 2015; Park et al., 2015). Here, SLC39A8 is linked to Cerebellar atrophy.
