title: Interstitial deletion 1p as a result of a de novo reciprocal 1p;2p translocation.
abstract: A 5-month-old female patient with psychomotor retardation and minor dysmorphisms is described. Cytogenetic analysis using high-resolution banding technique revealed an interstitial deletion of the short arm of one chromosome 1 (p21----p22.2) resulting from a de novo translocation t(1;2)(p22;p25).
