Summaries for CDSN Gene

Entrez Gene Summary for CDSN Gene

  • This gene encodes a protein found in corneodesmosomes, which localize to human epidermis and other cornified squamous epithelia. The encoded protein undergoes a series of cleavages during corneocyte maturation. This gene is highly polymorphic in human populations, and variation has been associated with skin diseases such as psoriasis, hypotrichosis and peeling skin syndrome. The gene is located in the major histocompatibility complex (MHC) class I region on chromosome 6. [provided by RefSeq, Dec 2014]

  • Hypotrichosis 2 (HYPT2) [MIM:146520]: A condition characterized by the presence of less than the normal amount of hair. Affected individuals have normal hair in early childhood but experience progressive hair loss limited to the scalp beginning in the middle of the first decade and almost complete baldness by the third decade. Body hair, beard, eyebrows, axillary hair, teeth, and nails develop normally. {ECO:0000269 PubMed:12754508}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Peeling skin syndrome 1 (PSS1) [MIM:270300]: A genodermatosis characterized by generalized, continuous shedding of the outer layers of the epidermis. Two main PSS subtypes have been suggested. Patients with non-inflammatory PSS (type A) manifest white scaling, with painless and easy removal of the skin, irritation when in contact with water, dust and sand, and no history of erythema, pruritis or atopy. Inflammatory PSS (type B) is associated with generalized erythema, pruritus and atopy. It is an ichthyosiform erythroderma characterized by lifelong patchy peeling of the entire skin with onset at birth or shortly after. Several patients have been reported with high IgE levels. {ECO:0000269 PubMed:20691404}. Note=The disease is caused by mutations affecting the gene represented in this entry. CDNS mutations are responsible for generalized, inflammatory peeling skin syndrome type B (PubMed:20691404). {ECO:0000269 PubMed:20691404}.
