The partial trisomy 4q is a strange chromosomal illness. This illness is caused by the duplication of a portion of chromosome 4. In most of the cases, it is the result of a balanced translocation in one of the progenitors. The "de novo" appearance is less common. We present a patient with a partial "de novo" duplication in the distal segment of the long arm of chromosome 4 (q31, q35), in association with Robertsonian translocation between chromosomes 14 and 21. This association has not been described previously. In the 4q duplication, the relationship between the phenotype and the parts of the duplicated segment is not well defined, although it seems clear that the renal anomalies and/or thumbs abnormalities are a characteristic manifestation. We have reviewed the literature and, of the cases previously described with trisomy q31-35, we came to the conclusion that this region of chromosome 4 may also be involved in constituting the "Syndrome of partial trisomy 4q" or Auriculo-acro-renal Syndrome". |
