ABSTRACT
OBJECTIVE@#To carry out prenatal diagnosis on a fetus with abnormal findings by ultrasonography and non-invasive prenatal testing.@*METHODS@#The fetus and both parents were subjected to chromosomal karyotyping and single nucleotide polymorphism array (SNP-array) analysis.@*RESULTS@#The karyotypes of both parents were normal. The fetus carried a 46,N,der(X;16)(q28;q22) unbalanced translocation. SNP-array analysis confirmed that the derived chromosomal fragment of the fetus has originated from 16q. The fetus was diagnosed with 16q partial trisomy syndrome.@*CONCLUSION@#Combined chromosomal karyotyping analysis and SNP-array can detect chromosomal aberrations at submicroscopic level and enable accurate diagnosis of the fetus.
