a: GTG-banding karyotype of PKS fetus in cord blood lymphocytes. Red arrow shows a supernumerary isochromosome 12p. b: Metaphase FISH using 12p telomere probe labeled green and 16 centromere probe labeled orange. Blue arrows show the normal chromosome 12. White arrows show the chromosome 16. Red arrow shows the isochromosome 12p. c: SNP-array analysis of uncultured cord blood. Blue arrow shows the log2 ratio. Red arrow shows the lines of copy number variants of 12p were between 2 and 3
