Confined trisomy 8 mosaicism of meiotic origin: a rare cause of aneuploidy in childhood cancer.

Abstract excerpt

Whether chromosome abnormalities observed in tumor cells may in some cases reflect low-grade somatic mosaicism for anomalies present already at zygote formation, rather than acquired somatic mutations, has for long remained a speculation. We here report a patient with Wilms tumor, where constitutional somatic mosaicism of trisomy 8 was detected in a previously healthy 2 ½-year-old boy. Single Nucleotide...
