WDR19 encodes IFT144, a member of the intraflagellar transport (IFT) complex A that drives retrograde ciliary transport.


- ciliopathies with skeletal anomalies and renal insufficiency due to mutations in the IFT-A Gene WDR19 (22019273)

  • A subset of ciliopathies, including Sensenbrenner syndrome, Jeune syndrome, and short-rib polydactyly syndromes (SRPS) are characterized by skeletal anomalies accompanied by multiorgan defects such as chronic renal failure and retinitis pigmentosa.
  • IFT144 has been found absent from the cilia of fibroblasts from one of the Sensenbrenner patients and that ciliary abundance and morphology is perturbed, demonstrating the ciliary pathogenesis.
  • Isolated nephronophthisis, Jeune syndrome, and Sensenbrenner syndromes are clinically overlapping disorders that can result from a similar molecular cause.
