Summaries for Joubert Syndrome 20

UniProtKB/Swiss-Prot : ⁷⁵ Joubert syndrome 20: 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.

MalaCards based summary : Joubert Syndrome 20, is also known as jbts20. An important gene associated with Joubert Syndrome 20 is TMEM231 (Transmembrane Protein 231). Affiliated tissues include liver and eye, and related phenotypes are respiratory insufficiency and global developmental delay

Disease Ontology : ¹² A Joubert syndrome that has material basis in compound heterozygous mutation in the TMEM231 gene on chromosome 16q23.
