Involvement in diseasei

Joubert syndrome 16 (JBTS16)1 Publication

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionAn autosomal recessive disorder characterized by oculomotor apraxia, variable coloboma, and rare kidney involvement. Neuroradiologically, it is characterized by 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 polydactyly.

Miscellaneous

TMEM138 and TMEM216 genes are adjacent and are aligned in a head-to-tail configuration. They share some cis regulatory region and display coordinated expression. Genes were joined by chromoaomal rearrangement at the amphiboan to reptile evolutionary transition around 340 million years ago (PubMed:22282472).1 Publication
