    Abstract:
    OBJECTIVE: To present the experience on prenatal diagnosis of Wolf-Hirschhorn syndrome (WHS) to further delineate the fetal presentation of this syndrome. STUDY DESIGN: This was a retrospective analysis of ten pregnancies with fetal WHS identified by chromosomal microarray (CMA). Clinical data were reviewed for these cases, including maternal demographics, indications for invasive testing, sonographic findings, CMA results and pregnancy outcomes. RESULTS: Three cases were diagnosed at the first trimester because of an increased NT or cystic hygroma. The remaining seven cases were identified at late gestation for abnormal ultrasound findings. CMA revealed 4p deletions to be terminal in all of the ten cases. Deletion sizes ranged from 2.05 to 19.02 Mb. CONCLUSION: Prenatal findings such as increased NT, severe and early onset intrauterine growth retardation, and renal dysplasia or oligohydramnios should warrant the diagnosis of WHS and invasive testing using CMA.
