A case reported by Kamate and Basavanagowda described a 14-year-old girl, born to a second-degree consanguineous couple with a normal birth history, who had seizures from the age of five months with clinical manifestations including ataxia, oculomotor apraxia, elevated alpha-fetoprotein (AFP), and a homozygous missense mutation in ARV1 [4]. Here, AFP is linked to cerebellar ataxia.
