Genes affected
TMEM67 (HGNC:28396): (transmembrane protein 67) The protein encoded by this gene localizes to the primary cilium and to the plasma membrane. The gene functions in centriole migration to the apical membrane and formation of the primary cilium. Multiple transcript variants encoding different isoforms have been found for this gene. Defects in this gene are a cause of Meckel syndrome type 3 (MKS3) and Joubert syndrome type 6 (JBTS6). [provided by RefSeq, Nov 2008]

Likely pathogenic, criteria provided, single submitterclinical testingPreventionGenetics, part of Exact SciencesJan 09, 2024The TMEM67 c.2528A>G variant is predicted to result in the amino acid substitution p.Tyr843Cys. This variant has been reported in the compound heterozygous state with a pathogenic TMEM67 variant in individuals with Meckel syndrome (Iannicelli et al 2010. PubMed ID: 20232449; Internal Data). This variant has not been reported in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. This variant is interpreted as likely pathogenic. -
