Özet

We report on a girl who presented with distinctive abducted hip and hyperextended knee. Cytogenetic analysis detected an extra derivative chromosome resulting from a balanced translocation in the mother and 3:1 segregation. Using array comparative genomic hybridization (CGH) in combination with conventional high resolution GTG banding, we designate the karyotype as 47, XX, +der(9)t(1;9)(q41;q21.32)mat, indicating tertiary trisomy of chromosome segments 1q41-qter and 9pter-9q21.32. A review and genotype-phenotype correlation suggested that the patient represented most of the manifestations of duplication of chromosome arms 1q and 9p. To our knowledge, a similar case has so far not been reported. (c) 2013 Wiley Periodicals, Inc.
