abstract: We describe a female child with complex cytogenetic anomalies consisting in partial trisomy of the short arm of chromosome 10, terminal deletion of the long arm of chromosome 2 and--at the same time--a mosaicism for X monosomy. To our knowledge, this is the first case reported in which 10p trisomy is associated to a 2qter deletion. Due to the scarcity of cases reported with pure trisomy, it has not been possible to define the 10p+ syndrome precisely yet. Comparison of our proband's phenotype to both the 2q37 deletion and 10p trisomy showed more features described in 2q37- subjects than in 10p+ ones. We also discuss the difficulties of genetic counseling in children with complex aberrations.
