Renal tubular dysgenesis due to twin-twin transfusion – http://id.who.int/icd/entity/122234138

Renal tubular dysgenesis due to twin-twin transfusion syndrome (TTTS) is an acquired form of renal tubular dysgenesis that develops in donor fetuses due to the uneven shunting of growth factor and nutrients to the kidney of the recipient and is characterised by absent or poorly developed proximal tubules, persistent oligohydramnios and consequently the Potter sequence (facial dysmorphism with large and flat low-set ears, lung hypoplasia, arthrogryposis and limb positioning defects).
