I don't know

Limited reports, single publication in 2012 reported AD and AR inheritance. Mechanism not well established. Pending additional reports.

2 Turkish sibs with Joubert syndrome with homozygous mutation in the ZNF423 gene.
Two additional patients with Joubert syndrome were found to carry heterozygous ZNF423 mutations , which caused a dominant-negative effect on protein function in cellular studies. Published variants not present in gnomAD at unexpected frequencies and minimal LoF variants in gnomAD
