The PER3rs772027021 SNP induces pigmentation phenotypes of dyschromatosis universalis hereditaria

PER3 rs772027021 SNP is identified to be associated with hyperpigmentation and/or hypopigmentation phenotype and the novel pathogenic variant of PER3 rs772027021 SNP probably contributed the pathogenesis of DUH. SASH1T525R mutation is confirmed to associate with DUH. A novel autosomal dominant inheritance DUH subtype with mild pigmentated phenotypes is caused by the PER3rs772027021 SNP.
