Combination of acanthosis nigricans benigna, obesity, short stature, cryptorchidism (see Maldescensus testis) and oligophrenia. In the neonatal period myotonia-like condition. 1% of affected patients suffer from tyrosinase-positive oculocutaneous albinism (OCA2: gene mutations on chromosome 15q as well as PWS; see also Angelman syndrome).

Data on frequency vary between 1/10,000 and 1/170,000 inhabitants.
