Hypomelanosis of Ito: involvement of chromosome aberrations in this syndrome.
The authors report on cytogenetic results of six patients with hypomelanosis of Ito. Karyotypes from peripheral lymphocytes prometaphases and skin fibroblasts metaphases were normal. A review of the literature revealed no specific chromosomal abnormality but a close association between mosaicism and HI syndrome. The X-chromosome was involved in 53% of the abnormal cases.
