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

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 10, 2022The c.293A>G (p.Y98C) alteration is located in exon 3 (coding exon 3) of the TTC14 gene. This alteration results from a A to G substitution at nucleotide position 293, causing the tyrosine (Y) at amino acid position 98 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
