Abstract: | A non-mongoloid boy born to a mongoloid mother is described. He showed aplasia of the left 5th finger and some clinical and dermatoglyphic features frequently found in Down's syndrome. Chromosome analysis revealed few hyperdiploid but no G-trisomic cells. An undetected G-trisomy mosaic, or a mechanism of extrachromosomal inheritance, and an embryonic development in a pathological milieu are discussed. |
