✦ Synopsis

We report on a male fetus with partial trisomy 2p21-2pter and monosomy 15q26-15qter due to t(2,15)(p21;q26). This fetus had a typical trisomy 2p phenotype including minor facial anomalies, musculoskeletal defects and two unusual findings: polydactyly and anencephaly. The observation of anencephaly adds support to the theory that genetic material mapping to chromosome band 2p24 is involved in neural tube development. In addition, we propose that a gene on 2p23 may play a role in the morphogenetic patterning of hands and feet. Am. J.

Major characteristics of the acrocallosal syndrome include severe mental retardation, agenesis or hypoplasia of the corpus callosum, and polydactyly of fingers and toes. In the past few years, anencephaly has also been noted, together with other midline defects. We report on a nonconsanguineous, Nor

We report on a child with apparent Sotos syndrome (cerebral gigantism) and partial duplication of the short arm of chromosome 20 mosaicism. Trisomy 20p11.2-p12.1 was diagnosed using cytogenetic and FISH studies. The somatostatin receptor 4 (SSTR4) gene is included in the duplicated segment. This sug
