Re-analysis of a retracted paper: Detection of chromosomal aberrations
SNP distribution analysis can also be applied to detect aneuploidy. In examining allele frequencies for each chromosome, abnormal chromosomes are assumed to have skewed distributions when paired chromosomes do not have the equal number of duplicates. As shown in Fig. 3A, chromosomal analysis showed abnormality of chromosome 8 in the STAP cells used in the original study. We can expect the peak allele frequency to occur at approximately 50% if a cell has two chromosomes from parents of different strains. The peak allele frequency of the STAP cells, however, was at approximately 33%, meaning that one of the two chromosomes appears to be duplicated leading to three copies of chromosome 8.
The STAP cells used in the experiments were derived from 129 and B6 cells, and the duplicated chromosome is presumed to be from the 129 parent because it contained only non-B6 SNP alleles. It is notable that trisomy 8 is the most common chromosomal aberration in mouse ESCs, with 31 of 97 examined cell lines reported to carry this abnormality (Mayshar et al. 2010). ESCs having trisomy 8 have a growth advantage, but chimeras will not transmit the mutation to the germ-line (Ben-David et al. 2013), and trisomy 8 in mice results in prenatal death by day 12 or 13 (Kim et al. 2013).
