title: A 2-Mb critical region implicated in the microcephaly associated with terminal 1q deletion syndrome.
abstract: Patients with distal deletions of chromosome 1q have a recognizable syndrome that includes microcephaly, hypoplasia or agenesis of the corpus callosum, and psychomotor retardation. Although these symptoms have been attributed to deletions of 1q42-1q44, the minimal chromosomal region involved has not been identified. Using microsatellite and single nucleotide polymorphism (SNP) markers, we have mapped the deleted regions in seven patients with terminal deletions of chromosome 1q to define a 2.0-Mb microcephaly critical region including the 1q43-1q44 boundary and no more than 11 genes.
