PRDX3 and aceruloplasminemia: Recently, a study shed light on the bi-allelic variations found in the PRDX3 gene that causes spinocerebellar ataxia, autosomal recessive type 32 [SCAR32; Online Mendelian Inheritance in Man (OMIM) #619862], often accompanied by characteristic MRI signal changes in the infratentorial region.1,2 To date, PRDX3 disease has been reported in nine cases from Arabian, Indian and European populations.2–4 In this report, we aim to further expand the genomic and clinical spectrum of PRDX3 disease by presenting two unrelated Korean patients with cerebellar ataxia.
