Which is exactly what I said. The genetic disorder did not directly limit the size of the dwarf's organs, but, rather, the size of the thoracic cavity limited the size of the organs - they were trying to grow to FULL SIZE in an ENCLOSED space. But this is the exception, not the rule - it's a complication that a dwarf can experience, but the majority do not.
