Autosomal recessive idiopathic basal ganglia calcification-10 (IBGC10) is a progressive neurologic disorder characterized by motor dysfunction, speech impairment, and impaired cognition. Brain CT imaging shows calcification in the bilateral globus pallidus, thalamus, and cerebellum (summary by Zhao et al., 2022). For a phenotypic description and a discussion of genetic heterogeneity of IBGC, see IBGC1 (213600). [from OMIM]
