Figure 2 Regions of long contiguous stretches of homozygosity (LCSH) over 5 Mb in length identified by SNP analysis in individuals V:11 (right track) and V:12 (left track). Chromosomes 1 to 12 are depicted in order from top left to right; chromosomes 13 to 22, X and Y are depicted in order from bottom left to right. The arrowed region on chromosome 13 shows the location of the SACS gene, contained within the LCSHs of indicated sizes. m
