Renal tubular dysgenesis

Disease definition

Renal tubular dysgenesis is a rare disorder of the fetus characterized by absent or poorly developed proximal tubules of the kidneys, persistent oligohydramnios, leading to Potter sequence (facial dysmorphism with large and flat low-set ears, lung hypoplasia, arthrogryposis and limb positioning defects), and skull ossification defects. It can be acquired during fetal development due to drugs taken by the mother or certain disorders (twin-twin transfusion syndrome, TTTS) or inherited in an autosomal recessive manner.
