Summaries for Palmoplantar Keratoderma I, Striate, Focal, or Diffuse

OMIM : 58 Striate palmoplantar keratoderma belongs to a group of skin diseases in which there is thickening of the skin on the palms and soles. The striate form is characterized by longitudinal hyperkeratotic lesions extending the length of each finger to the palm, and hyperkeratotic lesions are restricted to regions of the body where pressure and abrasion are greatest (summary by Hunt et al., 2001). Patients with diffuse or focal forms of keratoderma associated with mutation in the DSG1 gene have also been reported (Keren et al., 2005; Milingou et al., 2006). (148700)

MalaCards based summary : Palmoplantar Keratoderma I, Striate, Focal, or Diffuse, also known as keratosis palmoplantaris striata 1, is related to keratosis palmoplantaris striata ii. An important gene associated with Palmoplantar Keratoderma I, Striate, Focal, or Diffuse is DSG1 (Desmoglein 1). Affiliated tissues include skin, and related phenotypes are hyperhidrosis and nail dystrophy

UniProtKB/Swiss-Prot : 76 Palmoplantar keratoderma 1, striate, focal, or diffuse: A dermatological disorder characterized by thickening of the skin on the palms and soles, and longitudinal hyperkeratotic lesions on the palms, running the length of each finger.
