A Fetus with 17q23.1-q23.2 Microdeletion Presents with Primary Bilateral Lung Hypoplasia in Utero

Background:Patients with 17q23.1-q23.2 microdeletion syndrome have common features, including mild to moderate developmental delay; microcephaly; heart defects; and hand, foot, and limb abnormalities. Case Report: We describe a fetus with 2.14 Mb microdeletion involving 17q23.1-q23.2 and presenting...

Description
Summary:Background:Patients with 17q23.1-q23.2 microdeletion syndrome have common features, including mild to moderate developmental delay; microcephaly; heart defects; and hand, foot, and limb abnormalities. Case Report: We describe a fetus with 2.14 Mb microdeletion involving 17q23.1-q23.2 and presenting with primary bilateral lung hypoplasia in utero. The fetal biometry measurement and estimated fetal weight had a two-week delay but they were still above the 10th percentile. There were no other structural abnormalities. Primary lung hypoplasia is infrequent and has a poor prognosis, especially when bilateral. There are no reports of fetal survival with primary bilateral lung hypoplasia. Conclusion: This is the first report of the coexistence of primary lung hypoplasia and chromosome 17q23.1-q23.2 microdeletion detected during fetal life.
