Case 2

Arch Pediatr Adolesc Med. 1994;148(6):613-614. doi:10.1001/archpedi.1994.02170060067013

A 2550-G, MALE NEWBORN, 36 weeks of gestational age, was noted to have mild facial dysmorphism and was referred for a genetic evaluation. A sibling was said to have a chromosomal abnormality. These are indications for chromosomal analysis. A peripheral blood sample was obtained from the newborn, and cytogenetic procedures followed. All metaphase cells analyzed by routine trypsin-Giemsa banding suggested an interchromosomal insertional translocation (Figure 1). This impression was elegantly confirmed by fluorescence in situ hybridization (FISH) technique (Figure 2).
