METHODS: Chromosomal karyotype of umbilical cord blood sample derived from a 36-year-old pregnant woman was analyzed by G-banding analysis. After birth, the child was further analyzed with single nucleotide polymorphism microarray (SNP array) and fluorescence in situ hybridization (FISH) using 12pter/12qter probes. RESULTS: G-banding analysis showed that the fetus has a karyotype of 46,XY [77]/47,XY,+mar [23]. After birth, Affymetrix CytoScan 750K array analysis showed a segmental tetrasomy of arr [hg19] 12p13.33p11.1(173 786 - 34 835 641)x4 and a 34.6 Mb repeat at 12p13.33p11.1 with in the neonate. FISH analysis confirmed that 39% of cells harbored the 12p tetrasomy. CONCLUSION: Combined clinical examination, G-banded chromosomal karyotyping, FISH and microarray analysis can delineate the origin and fragments of small supernumerary marker chromosomes and diagnose PKS with precision.
