From: Characteristics and mechanisms of mosaicism in prenatal diagnosis cases by application of SNP array
SNP array and karyotype results of small supernumerary marker chromosomes. A SNP array revealed 15q11.2q13.1×2~6 and karyotype was 48,XX,+2mar[30]/47,XX,+mar[28]/46,XX[7] for case 32. B SNP array showed 21q11.2q21.1×2~4 and karyotype was 47,XY,+mar[13]/46,XY[15] for case 33. In addition, the SNP array of the mother was 21q11.2q21.1×2~3 and her karyotype was 47,XX,+mar[10]/46,XX[39]. C SNP array was (12)×2~3, 12p11.23p11.1×3 and karyotype was 47,XX,+mar for case 34. The presence of a choroidal fissure cyst malformation was detected via ultrasound examination
