RESUMO

Abstract BACKGROUND: Recent mutation analysis identified several missense mutations in CARD14 in psoriasis. OBJECTIVES: We performed the genomic sequence analysis on CARD14 in southern Chinese Han Cantonese with Psoriasis Vulgaris (PsV) to reveal more causative missense mutations. METHODS: A total of 131 patients with PsV and 207 matched controls were included. We conducted sequence analysis of all the exon and exon-intron boundaries of CARD14 in the group of PsV patients and subsequent case control analysis of potential sequence variants of significance. RESULTS: We found five rare mutations and four of them are annotated or reported. Only the variant (c.1291C>G) has not been reported and annotated, but the variant was also found in controls. No significant difference was detected among all rare variant allele frequencies of patients and controls. CONCLUSION: None of the new definite variants were pathogenic. The other pathogenic mutations for PsV are still elusive in our cohort.

RESUMO

AbstractA 43-year-old Chinese man presented with generalized hypohidrosis, which he had had since birth, without obvious abnormalities of other skin appendages except a sparse beard and axillary hairs. The sweat test revealed localized sweating on the face, axillae and palms. Histopathologic examination showed that the sweat glands were absent in the forearm and thigh, but some eccrine and apocrine sweat glands were present in the right axilla. S-100 was expressed in the nerve terminals surrounding the acini and ducts of the eccrine sweat glands, while PGP9.5 was positive in the acini of apocrine glands and the nerve terminals surrounding the eccrine glands in the axilla. To our knowledge, this is the first case of congenital idiopathic hypohidrosis in China.
