ABSTRACT
OBJECTIVE@#To carry out genetic testing for a pregnant woman with mild mental retardation, facial dysmorphism, and a history of adverse pregnancies and provide prenatal diagnosis for her.@*METHODS@#Routine G-banded karyotyping and single nucleotide polymorphism microarray (SNP-array) analysis were performed on the couple and amniotic fluid sample.@*RESULTS@#No karyotypic abnormality was found with the couple and amniotic fluid sample. SNP-array analysis showed that the woman has carried a 7.801 Mb microdeletion in 10q22.3q23.2, which involved 18 OMIM genes including CDHR1, BMPR1A, NRG3, GRID1 and LDB3, which are associated with facial abnormalities, developmental retardation, mental retardation and autism. The fetus also carried a 7.819 Mb deletion in the same region, while the father showed no abnormality.@*CONCLUSION@#Both the pregnant woman and her fetus have carried a 10q22.3q23.2 microdeletion, which has provided guidance for her subsequent pregnancy.
