Biallelic DAW1 variants reveal a tissue-specific role in heterotaxy without primary ciliary dyskinesia.
Defects in motile cilia cause a range of disorders, including heterotaxy (HTX), congenital heart disease (CHD), and primary ciliary dyskinesia (PCD). Although these conditions often co-occur, the genetic and mechanistic bases for tissue-specific manifestations remain poorly understood. Here, we identify compound hetero...
