Core Tip

Core Tip: The pure duplication of 19q is a rare chromosome abnormality that may affect a number of genes. Patients with 19q abnormality show a complicated syndrome such as developmental delay, dysmorphic features, and clinical nurse specialist malformations. To date, only 8 patients with partial trisomy of 19q have been reported. Here, we describe a girl with pure duplication of 19q, who was diagnosed with congenital esotropia, microcephaly, and gallbladder agenesis.
