Using a population sampling probability algorithm (PSAP) to analyze exome sequencing data [54], we identified an apparently homozygous stop-gain variant in ciliary and flagella associated protein 57 (CFAP57/WDR65; MIM: 614259; NM_001195831.2) the human ortholog of FAP57. The individual has classical symptoms of PCD that included bronchiectasis, neonatal respiratory distress, otitis media, and sinusitis. The gene discussed is CFAP57; the disease is primary ciliary dyskinesia.
