Deletion 15q21.1----q22.1 resulting from a paternal insertion into chromosome 5.
A 15 month old boy with an interstitial deletion 15q derived from a paternal insertion (5;15)(q31.3;q21.1q22.1) is described and compared with one other reported case. A beak like nose with hypoplastic nasal alae, a thin upper lip, failure to thrive in infancy with later onset of obesity, and severe mental retardation are features common to both.
