From: Prenatal diagnosis of complete paternal uniparental isodisomy for chromosome 3: a case report
Regions of homozygosity (ROH) in chromosome 3 identified with SNP array analysis of the fetus. a ChAS revealed a complete ROH across the entire chromosome (purple rectangle, blue arrow). b A whole chromosome view clearly shows the copy neutral ROH on chromosome 3 in the fetus (red arrow)
