Novel homozygous <i>C3orf67</i> gene variant associated with primary ciliary dyskinesia in a Saudi pediatric patient: A case report

This case highlights the importance of genetic studies in diagnosing PCD, particularly in communities with a high rate of consanguinity. The identification of a novel homozygous variant in the <i>C3orf67</i> gene expands the known genetic landscape of the disease. Further research is essential to clarify the functional role of <i>C3orf67</i> in ciliary biology and its contribution to PCD pathogenesis.
