Molecular cytogenetics, RFLP analysis and clinical characterization of a de novo trisomy 10p case.

A new case of a de novo trisomy 10cen-->10pter is described. The karyotype was exactly defined by high resolution banding and FISH analysis; the chromosome aberration was of maternal meiotic origin as demonstrated by RFLP analysis. Clinical data are reported and correlated with other trisomy 10p cases from the literature. A critical review of the literature was made to define the phenotype of trisomy 10p syndrome.
