Summaries for Laryngoonychocutaneous Syndrome

About this section
Genetics Home Reference:23 Laryngo-onycho-cutaneous (LOC) syndrome is a disorder that leads to abnormalities of the voicebox (laryngo-), finger- and toenails (onycho-), and skin (cutaneous). Many of the condition's signs and symptoms are related to the abnormal growth of granulation tissue in different parts of the body. This red, bumpy tissue is normally produced during wound healing and is usually replaced by skin cells as healing continues. However, in people with LOC syndrome, this tissue grows even when there is no major injury.

MalaCards based summary: Laryngoonychocutaneous Syndrome, also known as logic syndrome, is related to epidermolysis bullosa simplex, weber-cockayne type and localized junctional epidermolysis bullosa, non-herlitz type, and has symptoms including skin ulcer, abnormal pigmentation of the oral mucosa and abnormality of the toenails. An important gene associated with Laryngoonychocutaneous Syndrome is LAMA3 (Laminin Subunit Alpha 3). Affiliated tissues include skin, eye and lung.

UniProtKB/Swiss-Prot:67 Laryngoonychocutaneous syndrome: Autosomal recessive epithelial disorder confined to the Punjabi Muslim population. The condition is characterized by cutaneous erosions, nail dystrophy and exuberant vascular granulation tissue in certain epithelia, especially conjunctiva and larynx.
