Maybe it is difficult to extrapolate from mouse to human embryonic stem cells but one observed event is not even listed here.<\/p>\n

The results marked with a star have been observed<\/figcaption><\/figure>\n

The -15 genotype has a probability of less than 0.05%. For +1 genotype the probability is 0.09% and for the -4 deletion it is 3.74%.<\/p>\n

Looking therefore again at the Hong Kong slides of He Jiankui, I am getting doubts if the chromatogram \u00a0of embryo 2 \u00a0is correct interpreted even if we admit that the labels of embryo 1 and 2 have been switched..<\/p>\n

Color enhanced + sharpened version Hong Kong slide.\u00a0Unfortunately the chromatograms do not expand to the left also.<\/figcaption><\/figure>\n

Embryo 2 does not show\u00a0a clean<\/a>\u00a0 sequence at all and certainly not a -4\/+1 genotype as indicated. The sequence “ATTTTCCATACAG-ATTCAATTCTGGACTAAAATAAATACCT” isn’t even a human sequence at all.<\/p>\n\n
