Hypomelanosis of Ito: no entity, but a cutaneous sign of mosaicism

Am J Med Genet. 1999 Aug 6;85(4):346-50. doi: 10.1002/(sici)1096-8628(19990806)85:4<346::aid-ajmg7>3.0.co;2-1.

Abstract

Hypomelanosis of Ito is a neurocutaneous phenotype comprising pigmentary anomalies, neurological defects, structural malformations, and chromosomal abnormalities. It has been described as a distinct multisystem birth defect or, more specifically, as a neurocutaneous syndrome. The main purpose of this study is to provide evidence that this disorder does not exist as a syndrome. Rather, it is a causally nonspecific pigmentary disorder caused by genetic mosaicism.
