1 Homozygosity Mapping Places the Acrodermatitis Enteropathica Gene on Chromosomal Region 8q24.3 
Kun Wang, Elizabeth W. Pugh, Shari Griffen, Kimberly F. Doheny, Wedad Z. Mostafa, Mustafa M. al-Aboosi, Hatem el-Shanti, Jane Gitschier  The American Journal of Human Genetics  Volume 68, Issue 4, Pages (April 2001) DOI: /319514 Copyright © 2001 The American Society of Human Genetics Terms and Conditions

2 Figure 1 Jordanian pedigree with AE. A, Patient (corresponding to the filter card in the pedigree) showing perianal skin lesions. The perioral region shows an exudative and crusted area on an erythematous base, with irregular outline. The scalp hair is sparse, diarrhea is present, and the elbows and knees show scaly erythematous and thickened skin (psoriasiform). Periungal erythema and slightly swollen folds are present, and the nape of the neck shows slight psoriasiform rash. B, Haplotypes of the Jordanian pedigree, for 13 microsatellite markers at 8q24.3. Haplotypes were constructed by inspection, and those that are homozygous in affected individuals are boxed.

3 Figure 2 Pedigrees of seven consanguineous Egyptian families with genotypes of 10 microsatellite markers at 8q24.3. For compactness, only the relevant portions of the pedigrees are shown. Haplotypes/markers that are homozygous in affected individuals are boxed.

4 Figure 3 Graph of three-point and multipoint LOD scores, against distance (in cM), at 8q24.3. For sliding three-point analysis, the maximum LOD score is Homozygosity mapping gives a maximum LOD score of Mapmaker/Homoz was used for homozygosity mapping.
