ORPHA:97367Etiological subtype
What it is
A rare acquired form of renal tubular dysgenesis that develops in donor fetuses due to the shunting of blood flow to the kidney of the recipient and characterized 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).

Orphanet records these for the broader condition rather than for this specific form. They are a starting point, not a figure for this subtype — subtypes often differ, and some are defined by being rarer than the condition they sit under.
ICD-10 codes
ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.
