We report molecular and cytogenetic characterization of proximal deletion of chromosome 4q, del(4)(q12 --> q21.21) in a 131/2-year-old girl with short stature, mental retardation, developmental delay, hyperopia, exotropia, enamel defects, delayed tooth eruption and delayed puberty. We speculate that haploinsufficiency of the AMTN, ENAM and AMBN genes is most likely responsible for dental disorders, haploinsufficiency of the BMP2K genes is most likely responsible for ocular disorders, and haploinsufficiency of the EREG, AREG and BTC genes is most likely responsible for delayed puberty in this patient.
