Fig. 1From: Exploring the unique function of imprinting control centers in the PWS/AS-responsible region: finding from array-based methylation analysis in cases with variously sized microdeletionsSchematic diagram of the PWS/AS region. Horizontal gray line and dotted line indicate the range of conventional large deletion bounded by breakpoint (BP) 1 or 2 and BP 3. snoRNA genes are shown in ovals. Not all genes of the locus are shown, and the map is not to scaleBack to article page
