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.
In addition to confirming the previously identified asthma gene located on chromosome 17, researchers found another gene located on chromosome 1q31 was associated with an increased risk of childhood asthma in both children of European and African ancestry.
1 Two novel filaggrin mutations (S1302X and Q2397X) and two recurrent mutations (3321delA and K4671X) were identified in patients with atopic asthma. 2  Copy number variation within FLG makes a significant, dose-dependent contribution to atopic dermatitis risk. Loss-of-function mutations in the gene encoding FLG are linked with IV in Northern European and Japanese populations and results here demonstrate that FLG mutations are also associated with IV in a Bangladeshi population.
