Genes affected

TTC14 (HGNC:24697): (tetratricopeptide repeat domain 14) Predicted to enable nucleic acid binding activity. [provided by Alliance of Genome Resources, Apr 2022]

TTC14 links:

CCDC39 (HGNC:25244): (coiled-coil domain 39 molecular ruler complex subunit) The protein encoded by this gene is involved in the motility of cilia and flagella. The encoded protein is essential for the assembly of dynein regulatory and inner dynein arm complexes, which regulate ciliary beat. Defects in this gene are a cause of primary ciliary dyskinesia type 14 (CILD14). [provided by RefSeq, Jul 2011]
