Summaries for Joubert Syndrome 3

UniProtKB/Swiss-Prot : 75 Joubert syndrome 3: A disorder presenting with cerebellar ataxia, oculomotor apraxia, hypotonia, neonatal breathing abnormalities and psychomotor delay. Neuroradiologically, it is characterized by cerebellar vermian hypoplasia/aplasia, thickened and reoriented superior cerebellar peduncles, and an abnormally large interpeduncular fossa, giving the appearance of a molar tooth on transaxial slices (molar tooth sign). Additional variable features include retinal dystrophy and renal disease. Joubert syndrome type 3 shows minimal extra central nervous system involvement and appears not to be associated with renal dysfunction.

MalaCards based summary : Joubert Syndrome 3, also known as jbts3, is related to joubert syndrome with ocular anomalies and joubert syndrome 2, and has symptoms including ataxia An important gene associated with Joubert Syndrome 3 is AHI1 (Abelson Helper Integration Site 1). Affiliated tissues include eye, kidney and liver, and related phenotypes are low-set ears and ptosis

Disease Ontology : 12 A Joubert syndrome that has material basis in homozygous mutation in the AHI1 gene on chromosome 6q23.3.
