Figure 2

SNP array data for patient 1 (VII:1) and patient 2 (VII:3) and the unaffected sibling of patient 1 (VII:2). Patients 1 and 2 displayed a region of SNP homozygosity from 0–2.3 Mb. The unaffected sibling did not display this common SNP homozygosity. Dark blue, AA homozygous SNP call; mid-blue, BB homozygous SNP call; light blue, no call; white, AB heterozygous call.
