Although cerebellar ataxia was absent, the patient had a family history of autosomal dominant cerebellar ataxia: her maternal uncle (F3: II-5) was genetically confirmed with SCA3, and her mother (F3: II-4) had previously presented to our institution with limb ataxia and was diagnosed with SCA3. This evidence concerns the gene ATXN3 and aceruloplasminemia.
