background:
May be involved in cilia function and/or assembly.
Tissue specificity: Some isoforms are tissue-specific. Highly expressed in the prostate. Lower expression in the cerebellum, pituitary gland, fetal lung, and pancreas. In normal prostate, expressed in both basal and luminal epithelial cells. No expression detected in fibromuscular stromal cells, endothelial cells, or infiltrating lymphocytes. Uniformed expression in prostate adenocarcinoma cells.
Function:
May be involved in cilia function and/or assembly.
Subcellular Location:
Cell projection, cilium (By similarity). Cytoplasm, cytoskeleton, cilium basal body (By similarity). Note=Localizes to photoreceptor connecting cilia, to the base of motile cilia in brain ependymal cells and to the base of and along primary cilia in kidney cells (By similarity).

DISEASE:
Defects in WDR19 are the cause of cranioectodermal dysplasia type 4 (CED4) [MIM:614378]. CED4 is a disorder primarily characterized by craniofacial, skeletal and ectodermal abnormalities. Clinical features include craniosynostosis, narrow rib cage, short limbs, brachydactyly, hypoplastic and widely spaced teeth, sparse hair, skin laxity and abnormal nails. Nephronophthisis leading to progressive renal failure, hepatic fibrosis, heart defects, and retinitis pigmentosa have also been described.
Defects in WDR19 are the cause of asphyxiating thoracic dystrophy type 5 (ATD5) [MIM:614376]. ATD5 is an autosomal recessive chondrodysplasia characterized by a severely constricted thoracic cage, short-limbed short stature, and polydactyly. It often leads to death in infancy because of respiratory insufficiency. Retinal degeneration, cystic renal disease and hepatic disease can be present in affected individuals who survive early childhood.
Defects in WDR19 are the cause of nephronophthisis type 13 (NPHP13) [MIM:614377]. NPHP13 is an autosomal recessive disorder resulting in end-stage renal disease. It is a progressive tubulo-interstitial kidney disorder histologically characterized by modifications of the tubules with thickening of the basement membrane, interstitial fibrosis and, in the advanced stages, medullary cysts.
