Mutations in PERP Cause Dominant and Recessive Keratoderma. J Invest Dermatol 2018; 139:380-390.

Abstract
Investigation of genetic determinants of Mendelian skin disorders has substantially advanced understanding of epidermal biology. Here we show that mutations in PERP, encoding a crucial component of desmosomes, cause both dominant and recessive human keratoderma. Heterozygosity for a C-terminal truncation, which produces a protein that appears to be unstably incorporated into desmosomes, causes Olmsted syndrome with severe periorificial and palmoplantar keratoderma in multiple unrelated kindreds. Homozygosity for an N-terminal truncation ablates expression and causes widespread erythrokeratoderma, with expansion of epidermal differentiation markers. Both exhibit epidermal hyperproliferation, immature desmosomes lacking a dense midline observed via electron microscopy, and impaired intercellular adhesion upon mechanical stress. Localization of other desmosomal components appears normal, which is in contrast to other conditions caused by mutations in genes encoding desmosomal proteins. These discoveries highlight the essential role of PERP in human desmosomes and epidermal homeostasis and further expand the heterogeneous spectrum of inherited keratinization disorders.

Symmetrical acrokeratoderma: A peculiar entity in China? Clinicopathologic and immunopathologic study of 34 new cases. J Am Acad Dermatol 2014; 70:533-8. [PMID: 24388424 DOI: 10.1016/j.jaad.2013.10.061] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2013] [Revised: 10/21/2013] [Accepted: 10/29/2013] [Indexed: 11/20/2022]
Abstract
BACKGROUND Symmetrical acrokeratoderma seems to be a new disorder in China, and 138 cases have been reported in the Chinese literature. OBJECTIVE We sought to summarize the clinicopathologic features and immunophenotyping of inflammatory cells in 34 new cases. METHODS Clinical data of 34 patients were prospectively collected over 4 years. Histopathology and immunostaining of infiltrated cells were performed in 27 and 9 patients, respectively. RESULTS Brown to black hyperkeratotic patches were symmetrically distributed over the acral regions in 33 cases and on the scalp in 1 case, with a whitish change after water contact or sweating. The condition was aggravated in summer and alleviated in winter in 33 patients. History of ichthyosis vulgaris was seen in 23 cases. The typical histopathology included epidermal hyperkeratosis, acanthosis, and papillary dermal perivascular infiltrate of lymphohistiocytes. Number of CD3(+), CD4(+), and CD8(+) cells increased in lesional and perilesional skin compared with normal-appearing skin. The skin lesions developed slowly but were confined to the acral predilection sites after the mean follow-up of 25.4 ± 13.8 months. LIMITATIONS The follow-up time was short. CONCLUSION This disorder may represent a peculiar dermatosis that is frequently associated with ichthyosis vulgaris. No specific therapy is available for the disorder.
