- Disease or Syndrome
Atopic dermatitis (ATOD), also known as eczema, is a common chronic pruritic inflammatory skin disease with a strong genetic component. Onset typically occurs during the first 2 years of life (review by Soderhall et al., 2007).
Genetic Heterogeneity of Atopic Dermatitis
Many inflammatory diseases, such as atopic eczema, are genetically complex, with multiple alleles at several loci thought to be involved in their pathogenesis. Several susceptibility loci for atopic dermatitis have been identified: ATOD1 on chromosome 3q21, ATOD2 (605803) on chromosome 1q21, ATOD3 (605804) on chromosome 20p, ATOD4 (605805) on chromosome 17q25.3, ATOD5 (603165) on chromosome 13q12-q14, ATOD6 (605845) on chromosome 5q31-q33, ATOD7 (613064) on chromosome 11q13.5, ATOD8 (613518) on chromosome 4q22.1, and ATOD9 (613519) on chromosome 3p24.
