[[http://www.uniprot.org/uniprot/NAGAB_HUMAN NAGAB_HUMAN]] Defects in NAGA are the cause of Schindler disease (SCHIND) [MIM:[http://omim.org/entry/609241 609241]]. Schindler disease is a form of NAGA deficiency characterized by early onset neuroaxonal dystrophy and neurological signs (convulsion during fever, epilepsy, psychomotor retardation and hypotonia). NAGA deficiency is typically classified in three main phenotypes: NAGA deficiency type I (Schindler disease or Schindler disease type I) with severe manifestations; NAGA deficiency type II (Kanzazi disease or Schindler disease type II) which is mild; NAGA deficiency type III (Schindler disease type III) characterized by mild-to-moderate neurologic manifestations. NAGA deficiency results in the increased urinary excretion of glycopeptides and oligosaccharides containing alpha-N-acetylgalactosaminyl moieties. Inheritance is autosomal recessive.<ref>PMID:2243144</ref><ref>PMID:8782044</ref> Defects in NAGA are the cause of Kanzaki disease (KANZD) [MIM:[http://omim.org/entry/609242 609242]]; also known as NAGA deficiency type II or Schindler disease type II. Kanzaki disease is an autosomal recessive disorder characterized by late onset, angiokeratoma corporis diffusum and mild intellectual impairment.<ref>PMID:8040340</ref><ref>PMID:11251574</ref> | |||
