We have studied nine patients who presented with pigmentary anomalies of the skin in association with other congenital malformations in eight, we demonstrated chromosomal mosaicism in lymphocytes and/or skin fibroblasts a review of the literature revealed 25 similar examples of an association. Genetic mosaic/chimeric analysis in the zebraﬁsh mosaic: an organism consisting of cells of more than one genotype (derived from the same individual. Typically seen in zoology (but also discovered to a rare extent in human beings), a chimera is an animal that has two or more different populations of genetically distinct cells that originated in different zygotes if the different cells emerged from the same zygote, it is called a mosaicism.
Usually, individuals with a 46,xx/46,xy karyotype are considered as chimera rather than mosaic, even though a molecular analysis has not been provided a mosaic contains genetically different cells originating from a single zygote.
