title: De novo t(4;5)(q3100;q2200) with del(5)(q1500q2200). Tentative delineation of a 5q monosomy syndrome and assignment of the critical segment.
abstract: An 8-month-old boy with multiple malformations and psychomotor retardation was found to have a de novo t(4;5)(q1300;q2200) with del(5)(q1500q2200). The phenotypical comparison with 10 similar monosomic cases from the literature led us to tentatively delineate a 5q monosomy syndrome and to postulate the band 5q15 as the correspondent critical segment.
