Though, the multiple lentigo-like macules and the symmetrical hypopigmented patches, especially on the joint prominences, are the clinical characteristics of SASH1-related dyschromatosis but they are not commonly seen in patients with DUH (Zhang et al., 2013; Cui et al., 2013; Liu et al., 2014). The gene discussed is SASH1; the disease is dyschromatosis universalis hereditaria.
