Summaries for NAGA Gene

Entrez Gene Summary for NAGA Gene

  • NAGA encodes the lysosomal enzyme alpha-N-acetylgalactosaminidase, which cleaves alpha-N-acetylgalactosaminyl moieties from glycoconjugates. Mutations in NAGA have been identified as the cause of Schindler disease types I and II (type II also known as Kanzaki disease). [provided by RefSeq, Jul 2008]

GeneCards Summary for NAGA Gene

NAGA (N-Acetylgalactosaminidase, Alpha-) is a Protein Coding gene. Diseases associated with NAGA include schindler disease, type i and kanzaki disease. Among its related pathways are Lysosome and Glycosphingolipid biosynthesis - globo series. GO annotations related to this gene include protein homodimerization activity and alpha-N-acetylgalactosaminidase activity. An important paralog of this gene is GLA.

Disorders for NAGA Gene

(2) OMIM Diseases for NAGA Gene (104170)


  • Schindler disease (SCHIND) [MIM:609241]: 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. {ECO:0000269 PubMed:2243144, ECO:0000269 PubMed:8782044}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Kanzaki disease (KANZD) [MIM:609242]: Autosomal recessive disorder characterized by late-onset, angiokeratoma corporis diffusum and mild intellectual impairment. {ECO:0000269 PubMed:11251574, ECO:0000269 PubMed:8040340}. Note=The disease is caused by mutations affecting the gene represented in this entry.
