Abstract

The function and position of the internal organs within the human body are based on left‑right (LR) asymmetry. Human LR asymmetry disorders are characterized by abnormal LR asymmetric arrangement of the internal organs resulting from defective embryonic nodal cilia and nodal signaling pathway. The coiled‑coil domain containing 114 gene (CCDC114) is related to the biogenesis of cilia and attachment of the outer dynein arms (ODAs) to the axoneme of cilia. Mutations in the CCDC114 gene are reported to cause a subtype of primary ciliary dyskinesia (PCD) named ciliary dyskinesia, primary, 20 (CILD20). Patients with CCDC114 mutations present with a type of ciliopathy with high clinical heterogeneity. In the present study, a Han‑Chinese patient with situs inversus was recruited. Exome sequencing was performed on this patient combined with variant validation by Sanger sequencing. A homozygous variant c.584T>C (p.L195P) in the CCDC114 gene was identified as the likely genetic cause for situs inversus in this patient. The findings of our study extend the mutational spectrum of the CCDC114 gene, and contribute to clarifying the pathogenesis of human ciliopathies and benefit genetic counseling.
