[摘要]：Trisomy 12p syndrome is a rare chromosomal abnormality, which presents with facial dysmorphism, moderate to severe psychomotor retardation and generalized hypotonia. Here we present the prenatal sonographic findings investigated of a fetus in prenatal diagnosis with a de nova trisomy of 12p identified by array-comparative genomic hybridization (aCGH).
