Summaries for Joubert Syndrome 6

OMIM : 57 Joubert syndrome is an autosomal recessive disorder presenting with psychomotor delay, hypotonia, ataxia, oculomotor apraxia, and neonatal breathing abnormalities. Neuroradiologically, Joubert syndrome is characterized by peculiar malformation of the midbrain-hindbrain junction known as the 'molar tooth sign' (MTS) consisting of cerebellar vermis hypoplasia or aplasia, thick and maloriented superior cerebellar peduncles, and abnormally deep interpeduncular fossa (Romano et al., 2006). For a phenotypic description and a discussion of genetic heterogeneity of Joubert syndrome, see 213300. (610688)

MalaCards based summary : Joubert Syndrome 6, also known as jbts6, is related to meckel syndrome, type 2 and meckel syndrome, type 4, and has symptoms including ataxia An important gene associated with Joubert Syndrome 6 is TMEM67 (Transmembrane Protein 67), and among its related pathways/superpathways are Regulation of PLK1 Activity at G2/M Transition and Organelle biogenesis and maintenance. Affiliated tissues include eye, kidney and liver, and related phenotypes are intellectual disability and ataxia

Disease Ontology : 12 A Joubert syndrome that has material basis in homozygous or compound heterozygous mutation in the TMEM67 on chromosome 8q22.

UniProtKB/Swiss-Prot : 75 Joubert syndrome 6: 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.
