title: Partial 4q trisomy. Apropos of 3 cases.
abstract: Three observations of partial trisomy 4q are reported: the first due to a familial translocation the second to a de nove translocation, the third to a "mirror" duplication. The very characteristic phenotype is compared to that of 4 other patients already reported in the literature. The most evocatory symptoms include: absent or poorly indicated nose bridge; pursed lips; shortness of the philtrum; and constant existence of a fold on the antitragus continuing the anthelix reachinghe insertion of the pinna.
