title: Trisomy 20q13 --> 20qter in a girl with multiple congenital malformations and a recombinant chromosome 20 inherited from a paternal inversion (20)(p13q13.1): clinical report and review of the trisomy 20q phenotype.
abstract: We report on a patient with a rec(20)dup(20q) chromosome abnormality derived from a paternal chromosome 20 inversion [inv(20)(p13q13.1)]. The rearrangement results in a duplication of 20q13.1 to 20qter and a deletion of 20p13 to 20pter. The patient is a girl with craniofacial features and multiple congenital malformations that overlap with the abnormalities previously described in trisomy 20q syndrome. To our knowledge this is the first report of a patient with rec(20)dup 20q.
