Missense Variants in the Second Transmembrane Domain of TMEM17 Disrupt Its Stability and Function and Lead to a Wide Phenotypic Spectrum of Ciliopathies.
Ciliopathies are rare genetic disorders characterized by significant genetic and phenotypic variability. Over 140 proteins localized to primary cilia, which are sensory organelles essential for vertebrate development, are implicated. TMEM17 encodes a transmembrane protein at the ciliary transition zone and was previously proposed as a potential ciliopathy gene, based on reports of individuals from two families with orofaciodigital syndrome type 6 (OFD6) and Joubert syndrome (JS). Here, we report two unrelated fetuses with occipital encephalocele, polydactyly, and kidney cysts, in whom exome sequencing identified a founder homozygous missense variant (Arg94Trp) in TMEM17, affecting a highly conserved residue. This expands the TMEM17-associated phenotypic spectrum to include Meckel syndrome (MKS). Comprehensive functional analyses of all known TMEM17 variants, using patient tissues/cells and a C. elegans model system, demonstrate a loss-of-function mechanism. Our study reveals severe functional consequences, including TMEM17 destabilization and mislocalization, anomalies in cilium composition and function, and abrogation of Sonic Hedgehog signaling. These experiments confirm the pathogenicity of all TMEM17 variants and underscore its essential role at the ciliary transition zone. Collectively, our findings establish TMEM17 as a bona fide ciliopathy gene, associated with a wide phenotypic spectrum ranging from viable syndromes (OFD6 and JS) to a fetal-lethal condition (MKS).
CRISPR-Cas9-Generated TXNDC15 c.560delA Homozygous Mouse Model Exhibits Meckel-Gruber Syndrome Phenotype.
To determine whether TXNDC15 variation causes Meckel-Gruber syndrome (MKS), we assessed the pathogenicity of the frameshift variant c.560delA. A CRISPR-Cas9 generated mouse model carrying the equivalent Txndc15 c.512delA mutation was analyzed at embryonic day 15.5. Homozygous Txndc15mt/mt embryos displayed the complete MKS phenotype-fetal lethality, exencephaly, omphalocele, post-axial polydactyly, and polycystic kidneys-together with markedly reduced TXNDC15 protein in brain, liver, and kidney. These findings confirm TXNDC15 as a bona fide MKS disease gene.
Ciliopathy-related B9 protein complex regulates ciliary axonemal microtubule posttranslational modifications and initiation of ciliogenesis.
Ciliary dysfunction results in multiorgan developmental diseases, collectively known as ciliopathies. The B9D1-B9D2-MKS1protein complex maintains the gatekeeper function at the ciliary transition zone (TZ). However, the function of B9 proteins and the mechanisms underlying why different variants in the same B9 gene cause different ciliopathies are not fully understood. Here, we investigated the function of B9 proteins and revealed 2 critical functions. First, the B9 complex interacted with and anchored TMEM67 to the TZ membrane. Disruption of the B9-TMEM67 complex reduced posttranslational modifications of axonemal microtubules due to deregulation of tubulin-modifying enzymes within cilia. Second, B9 proteins localized to centrioles prior to ciliogenesis, where they facilitated the initiation of ciliogenesis. In addition, we identified B9D2 variants in a cohort of patients with Joubert syndrome. We found that Joubert syndrome-associated B9D2 variants primarily affected axonemal microtubule modifications without disrupting ciliogenesis, whereas the Meckel syndrome-associated B9D2 variant disrupted both ciliogenesis and axonemal microtubule modifications. Thus, besides its role as a gatekeeper for ciliary membrane proteins, the B9 complex also controls axonemal microtubule posttranslational modifications and early stages of ciliogenesis, providing insights into the distinct pathologies arising from different variants of the same gene.
Biallelic Variants in TMEM17 Cause Meckel-Gruber Syndrome Within the Ciliopathy Spectrum.
TMEM17 encodes a transition zone protein essential for ciliary function. Three cases with homozygous variants in TMEM17 in primary ciliopathies (Joubert and Oral-Facial-Digital syndrome) have been reported. We investigated whether biallelic TMEM17 variants contribute to primary ciliopathies. We queried our Biodatabank and evaluated the gene-disease relationship (GDR) according to the ClinGen recommendations. Four unrelated patients (four families) were identified with a clinical diagnosis of Meckel-Gruber syndrome (MGS) and novel homozygous variants: NM_198276.3:c.4del p.(Glu2Serfs*58); NM_198276.3:c.366dup p.(Pro123Thrfs*9); and NM_198276.3:c.368C>G p.(Pro123Arg). A fifth family lost three foetuses with MGS phenotype, both parents are heterozygote carriers (NM_198276.3:c.4del p.(Glu2Serfs*58)) but biological material from the foetuses was not available. The cases in this study had a severe prenatal phenotype, including encephalocele, polycystic kidney dysplasia, and polydactyly, leading to early lethality. This study strengthens the gene-disease association of TMEM17, upgrading it from "limited" to "moderate." We expand the phenotypic spectrum, ranging from MGS-with prenatal onset and early lethality-to Oral-Facial-Digital and Joubert syndromes. Our findings indicate that loss-of-function variants may underlie the most severe TMEM17 ciliopathy manifestations, suggesting a potential genotype-phenotype correlation.
Cleavage of the Meckel-Gruber syndrome protein TMEM67 by ADAMTS9 uncouples Wnt signaling and ciliogenesis.
TMEM67 mutations cause Meckel-Gruber syndrome and other related ciliopathies. TMEM67 is involved in both ciliary transition zone assembly, and non-canonical Wnt signaling mediated by its extracellular domain. How TMEM67 performs these two separate functions is not known. We identify a cleavage motif in the extracellular domain of TMEM67 cleaved by the extracellular matrix metalloproteinase ADAMTS9. This cleavage regulates the abundance of two functional forms: a C-terminal portion which localizes to the ciliary transition zone regulating ciliogenesis, and a non-cleaved form which regulates Wnt signaling. By characterizing three TMEM67 ciliopathy patient variants within the cleavage motif utilizing mammalian cell culture and C. elegans, we show the cleavage motif is essential for cilia structure and function, highlighting its clinical significance. We generated a non-cleavable TMEM67 mouse model which develop severe ciliopathies phenocopying Tmem67-/- mice, but in contrast, transduces normal Wnt signaling, substantiating the existence of two functional forms of TMEM67.
