title: Interstitial deletion of chromosome 2 (p23p25).
abstract: We report a patient with a de novo interstitial deletion of the short arm of chromosome 2 (p23p25). The patient had microcephaly with prominent forehead and occiput, narrow rectangular face, clinodactyly, failure to thrive, delayed psychomotor development, and seizures. Maternal serum alpha-fetoprotein was undetectable at 18 weeks of gestation. Heterozygosity at the red cell acid phosphatase locus (SRO-2p25) and normal levels of red cell malate dehydrogenase (SRO-2p23) are findings consistent with the presence of genetic material from bands 2p25 and 2p23.
