24886560 describe four patients with mild Joubert phenotypes who carry pathogenic mutations in either MKS1 or B9D1, two genes previously implicated only in Meckel syndrome
21493627 B9D1 is a novel Meckel syndrome gene
19208769 MKS-1 and MKS-1-related proteins 1 and 2 (MKSR-1/EPPB9, MKSR-2/B9D2), localize to transition zones/basal bodies of sensory cilia; subcellular localization is largely co-dependent, pointing to a functional relationship between the proteins
18337471 Ciliary transition zone localization. Functions in a module with related proteins (MKS1 and B9D1) that cooperates with nephrocystins in ciliogenesis.
