- have a significant incidence of Wilms' tumor;
- for this reason, abdominal ultrasonography should not only be part of initial evaluation but should be performed yearly during the patients' growing years;
- syndromes associated with hemihypertrophy:
- Beckwith-Wiedemann syndrome
- Klippel-Trénaunay-Weber syndrome
- Proteus syndrome

- brachydactyly type C:
- an autosomal dominant disorder with markedly variable penetrance;
- incomplete gene expression:
- shortening limited to the middle phalanges and the first metacarpal;
- elongation of the radial side of the base of the second proximal phalanx;
- complete gene expression:
- shortening of all the metacarpals (thumb most affected)
- brachymesophalangy (shortening of the middle phalanges);
- shortening of the proximal phalanges of the index and middle fingers, with the proximal phalanges of the ring and small fingers of normal length;
- elongation of the radial side of the base of the second proximal phalanx resulting in a trapezoidal shaped epiphysis;
- ulnar deviation at the second and third MP joints and hypersegmentation (extra phalanx) of the index and middle fingers.
