PLA2G6 and Dystonia: A wide range of diseases can cause dystonia combined with ataxia in pediatric populations, including autosomal recessive cerebellar ataxias such as ataxia–telangiectasia, inborn errors of metabolism (IEMs), particularly the subgroup of lysosomal storage disorders (LSDs), such as Niemann–Pick disease type C (NPC), GM1 gangliosidosis, and fucosidosis, as well as neurodegenerative syndromes like PLA2G6-associated neurodegeneration and DYT-SQSTM1 syndrome.
