Abstract:
Interstitial deletion of the short arm of chromosome 1 is rare. Eleven different breakpoints have been described in 12 children. We report a patient with del(1)(p32.1p32.3). Only one of the previously reported patients had an apparent identical deletion to that of the present case. The phenotypes of the two patients are strikingly similar. Distinctive features include excessive weight gain during the first 30 months, macrocephaly, frontal bossing, rounded face, mild synophyrs, slightly upslanting eyes, short palpebral fissures, broad nasal bridge, low set ears, prominent philtrum, long eyelashes, and delayed psychomotor development.
