Fig. 2From: Cytogenetic and molecular analysis of distal 4q duplication with distinctive phenotype using single-nucleotide polymorphism arrayThe NIPT results in the fetus of pedigree 2. The results of NIPT screening indicated a duplication of chromosome 4 and a deletion of chromosome X. A: The result showed a higher Z-score in distal chromosome 4, indicating a duplication of 4q in the fetus. B: A lower Z-score was observed in chromosome Xp, suggesting a deletion of chromosome XpBack to article page
