A novel compound heterozygous mutation in DNAH5 in a Korean neonate with primary ciliary dyskinesia

ABSTRACT

Primary ciliary dyskinesia (PCD) is a genetically heterogeneous disease affecting motile cilia. A female neonate was hospitalized with respiratory distress 72 hours after birth and showed concurrent situs inversus. She was identified to have compound heterozygous mutations in DNAH5 c.5647C>T, p.Arg1883Ter (nonsense mutation) and c.10810dupA, p.Ile3604AsnfsTer2 (frameshift mutation). Sanger sequencing confirmed that they were inherited from her father and mother, respectively, and she was diagnosed with PCD. The c.10810dupA is a novel DNAH5 mutation that has never been reported. To the best of our knowledge, this is the first report describing DNAH5 mutations in a Korean patient with PCD.
