Summaries for Pachyonychia Congenita 1

About this section
Genetics Home Reference : 25 Pachyonychia congenita is a condition that primarily affects the skin and nails. The signs and symptoms of this condition usually become apparent within the first few years of life. Almost everyone with pachyonychia congenita shows some signs of hypertrophic nail dystrophy, which causes the fingernails and toenails to become thick and abnormally shaped. Most affected children also develop very painful blisters and calluses on the soles of the feet and, less commonly, on the palms of the hands. This condition is known as palmoplantar keratoderma. Severe blisters and calluses on the feet usually first begin to form in childhood when they first start to walk, and can make walking painful or impossible. Pachyonychia congenita can have several additional features, which vary among affected individuals. These features include thick, white patches on the tongue and inside of the cheeks (oral leukokeratosis); bumps called follicular keratoses that develop around hair follicles on the elbows, knees, and waistline; cysts in the armpits, groin, back, or scalp; and excessive sweating on the palms and soles (palmoplantar hyperhidrosis). Some affected individuals also develop widespread cysts called steatocystomas, which are filled with an oily substance called sebum that normally lubricates the skin and hair. Some babies with pachyonychia congenita have prenatal or natal teeth, which are teeth that are present at birth or in early infancy. In some cases, pachyonychia congenita can affect the voice box (larynx), causing hoarseness or breathing problems. Researchers used to distinguish pachyonychia congenita as one of two types, PC-1 or PC-2, based on the genetic cause and pattern of signs and symptoms. However, as more affected individuals were identified, it became clear that the features of the two types overlapped considerably. Now researchers prefer a description of pachyonychia congenita based on the gene that is altered.

MalaCards based summary : Pachyonychia Congenita 1, also known as pachyonychia congenita, is related to pachyonychia congenita 2 and steatocystoma multiplex, and has symptoms including hoarseness An important gene associated with Pachyonychia Congenita 1 is KRT16 (Keratin 16), and among its related pathways/superpathways are Estrogen signaling pathway and Developmental Biology. The drugs Pregabalin and Morphine have been mentioned in the context of this disorder. Affiliated tissues include skin, tongue and lung, and related phenotypes are palmoplantar keratoderma and oral leukoplakia

Disease Ontology : 12 A syndrome that is characterized by hypertrophic nails and hyperkeratosis of the hands and feet and has material basis in gene mutations that result in changes in keratin.

NIH Rare Diseases : 52 Pachyonychia congenita (PC) is a rare inherited condition that primarily affects the nails and skin. The fingernails and toenails may be thickened and abnormally shaped . Affected people can also develop painful calluses and blisters on the soles of their feet and less frequently on the palms of their hands (palmoplantar keratoderma ). Additional features include white patches on the tongue and inside of the mouth (leukokeratosis); bumps around the elbows, knees, and waistline (follicular hyperkeratosis); and cysts of various types including steatocystoma. Features may vary among affected people depending on their specific mutation . PC is divided into 5 types based on the specific keratin gene involved: PC-K6a , PC-K6b , PC-K6c , PC-K16 , and PC-K17 . All forms are inherited in an autosomal dominant manner. Treatment is based on the signs and symptoms present in each person.

OMIM : 56 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). (167200)

KEGG : 36 Pachyonychia congenita (PC) is a group of autosomal dominant skin disorders characterized by hypertrophic nail dystrophy accompanied by other features of ectodermal dysplasia, prominently painful palmoplantar keratoderma. Additional clinical features include follicular hyperkeratosis, leukokeratosis of the oral mucosa, and various cysts (steatocysts and pilosebaceous cysts). It is caused by a mutation in one of four keratin genes KRT6A, KRT6B, KRT16, or KRT17.

UniProtKB/Swiss-Prot : 73 Pachyonychia congenita 1: An autosomal dominant ectodermal dysplasia characterized by hypertrophic nail dystrophy resulting in onchyogryposis (thickening and increase in curvature of the nail), palmoplantar keratoderma, follicular hyperkeratosis, and oral leukokeratosis. Hyperhidrosis of the hands and feet is usually present.
