A previous study detected three different mutations of DNAAF3 in PCD individuals: c.323T>C (p.Leu108Pro) in exon 3 creating missense mutation predicted to be ‘probably damaging’, c.406C>T (p.Arg136X) in exon 4 creating nonsense mutation, and c.762_763insT in exon 6 (p.Val255CysfsX12), creating a predicted frameshift that generates 11 novel amino acids after a p.Val255Cys change followed by a premature stop codon.27 This evidence concerns the gene DNAAF3 and primary ciliary dyskinesia.
