Expanding Stuhrmann and Nuber's findings and our own previous work providing photographic evidence of dyschromatosis presenting as large hyperpigmented bodies on DUH‐affected individuals 7, 28, 36, we believe that we have discovered the first locus associated with autosomal‐dominant DUH, identifying SASH1 as the causative gene of autosomal‐dominant DUH. This evidence concerns the gene SASH1 and Dyschromatosis universalis.
