Summaries for Pachyonychia Congenita 2

OMIM : 58 Pachyonychia congenita (PC) is an autosomal dominant genodermatosis with the main clinical features of hypertrophic nail dystrophy, painful and highly debilitating plantar keratoderma, oral leukokeratosis, and a variety of epidermal cysts. Although the condition had previously been subdivided clinically into Jadassohn-Lewandowsky PC type 1 and Jackson-Lawler PC type 2, patients with PC were later found to have a mixed constellation of both types, leading to a classification of PC based on genotype (summary by Sybert, 2010; Eliason et al., 2012; McLean et al., 2011). For a discussion of genetic heterogeneity of pachyonychia congenita, see 167200. (167210)

MalaCards based summary : Pachyonychia Congenita 2, also known as pachyonychia congenita, type 2, is related to pachyonychia congenita 1 and steatocystoma multiplex, and has symptoms including hoarseness An important gene associated with Pachyonychia Congenita 2 is KRT17 (Keratin 17), and among its related pathways/superpathways are Developmental Biology and Cytoskeletal Signaling. The drugs Bupivacaine and Ibuprofen have been mentioned in the context of this disorder. Affiliated tissues include prostate, and related phenotypes are nail dystrophy and sparse scalp hair

UniProtKB/Swiss-Prot : 76 Pachyonychia congenita 2: An autosomal dominant ectodermal dysplasia characterized by hypertrophic nail dystrophy resulting in onchyogryposis (thickening and increase in curvature of the nail), palmoplantar keratoderma and hyperhidrosis, follicular hyperkeratosis, multiple epidermal cysts, absent/sparse eyebrow and body hair, and by the presence of natal teeth.
