TMEM107

Chr 17AR

transmembrane protein 107

Also known as: GRVS638, JBTS29, MKS13, PRO1268

This gene encodes a transmembrane protein that is a component of the primary cilia transition zone and regulates ciliogenesis and ciliary protein composition. Mutations cause autosomal recessive ciliopathies including Meckel syndrome, Joubert syndrome, and orofaciodigital syndrome. The gene shows high constraint against loss-of-function variants, reflecting its critical role in ciliary function and embryonic development.

This gene has evidence for multiple mechanisms of pathogenicity (gain-of-function and dominant-negative). Both the Badonyi & Marsh prediction and the broader genomic evidence point to gain-of-function as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.

Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
