Interstitial deletion of chromosome 1 (q23–25). Report of a case

Abstract
We describe a 3‐month‐old female with a de novo interstitial deletion of the long arm of chromosome 1 (1q23–25). Clinical features are failure to thrive, psychomotor retardation, cleft lip and palate, short metacarpals, metatarsals and fingers and a severe congenital heart disease. The four previously reported patients with the same deletion share with ours the distinctive pattern of anomalies of the face and limbs; therefore, it seems now possible to delineate a proximal 1q deletion syndrome.
