Germline duplication of chromosome 2p and neuroblastoma.

Germline duplication of chromosome 2p and neuroblastoma.

A child with a germline duplication of chromosome 2p, 46,XY,der(13)t(2;13)(p23;q34), who developed a fatal neuroblastoma confirmed at necropsy is reported. Fluorescent in situ hybridisation studies showed chromosome 2p (p23-pter) duplicated on chromosome 13 (q34). The clinical features of the present case shared many similarities to previous reports of trisomy 2p and there have been two cases d...

Chromosome Duplication (14q) and The Genotype Phenotype Correlation

[Chromosome abnormalities in neuroblastoma].

The case is briefly reported of a 7-month-old boy with a disseminated neuroblastoma, whose marrow showed neuroblastoma rosettes and on direct examination on two occasions revealed a high proportion of cells with 48 chromosomes forming an abnormal cell line.

A Rare Case of Duplication of Chromosome 2 (q31.3q36.3) in a 4.5-year-old Boy and Review of the Literature

De novo duplication of 2q is very rare. Most cases of 2q duplications result from familial translocations, and are associated with simultaneous monosomy of another chromosome segment. To our knowledge and search in English literature there are less than 20 reported cases of isolated 2q duplication. Hereby we introduce a 4.5-year-old Iranian boy of a non-consanguineous marriage who was referred ...
