Abstract

Primary ciliary dyskinesia (PCD) is a rare hereditary disease. We herein report two sisters in their 20s with suspected PCD. They were both born at full term and did not have situs inversus. Chest computed tomography showed similar signs of bronchiectasis in both siblings. Genetic examinations of the family confirmed that the sisters both harbored a homozygous variant in the growth-arrest-specific 2-like 2 (GAS2L2) gene. This is the third report of a family with PCD caused by a GAS2L2 variant.

Keywords: GAS2L2; bronchiectasis; gene; primary ciliary dyskinesia; whole-exome sequencing.
