Primary Familial Brain Calcification (Fahr Disease) Due to a Novel Mutation in Solute Carrier 20 A2 Gene.

Bilateral symmetrical calcification of striatum and pallidum with or without involvement of other brain structures is a rare radiological finding. Genetic causes predominates once hypoparathyroidism is ruled out. Clinical features include a variable combination of neuropsychiatric and motor symptoms, including dystonia, Parkinsonism, ataxia, psychosis, dementia, chorea, and frontal-subcortical cognitive dysfunction. One third of primary familial brain calcification is asymptomatic. Solute carrier 20 A2 gene mutation accounts for the majority of primary familial brain calcification. Here we describe a case of primary brain calcification due to a novel mutation in Solute carrier 20A gene in a 55-year-old woman.
