Heterotaxy v1.27 EFCAB1 Chirag Patel gene: EFCAB1 was added
gene: EFCAB1 was added to Heterotaxy. Sources: Literature
Mode of inheritance for gene: EFCAB1 was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: EFCAB1 were set to PMID: 36727596
Phenotypes for gene: EFCAB1 were set to Primary ciliary dyskinesia and heterotaxy, no OMIM #
Review for gene: EFCAB1 was set to GREEN
Added comment: WES in 3 individuals with laterality defects and respiratory symptoms, identified homozygous pathogenic variants in CLXN (EFCAB1). They found Clxn expressed in mice left-right organizer. Transmission electron microscopy depicted outer dynein arm (ODA) defects in distal ciliary axonemes. Immunofluorescence microscopy revealed absence of CLXN from the ciliary axonemes, absence of the ODA components DNAH5, DNAI1 and DNAI2 from the distal axonemes, as well as mislocalization or absence of DNAH9. Additionally, CLXN is undetectable in ciliary axonemes of individuals with defects in the outer dynein arm docking (ODA-DC) machinery: ODAD1, ODAD2, ODAD3 and ODAD4. Moreover, SMED-EFCAB1-deficient planaria displayed ciliary dysmotility.
