KCTD7-related progressive myoclonic epilepsy: report of three Indian families and review of literature

We report four individuals from three Indian families presenting with an initial period of normal development, progressive myoclonic seizures followed by neuroregression and an abnormal electroencephalogram. We identified two novel missense variants, c.458G>C p.(Arg153Pro) and c.205C>G p.(Leu69Val) and one known disease-causing variant, c.280C>T p.(Arg94Trp) in KCTD7 by exome sequencing. We review the literature of 67 individuals with variants in KCTD7. Our study expands the molecular spectrum of KCTD7-related progressive myoclonic epilepsy.
