The term cellulitis is commonly used to indicate a nonnecrotizing inflammation of the skin and subcutaneous tissues, a process usually related to acute infection that does not involve the fascia or muscles. Cellulitis is characterized by localized pain, swelling, tenderness, erythema, and warmth.
The regions on chromosomes 7 and 12 may coincide with the asthma and atopy loci on the same chromosomes. Polymorphism in the IL1 cluster on chromosome 2 has also been shown to influence the severity of the disease (95, 96).
Largest study to date of rare genetic variants and asthma risk finds few associations. Despite a strong suspected link between genetics and asthma, commonly found genetic mutations account for only a small part of the risk for developing the disease -- a problem known as missing heritability.
