Monday, investigators from the Guangdong Province Health Commission reported that "the case was first identified as an explicitly prohibited human embryo reproductive activity for reproductive purposes performed by He Jiankui," Xinhua reported. The Commission added that the researcher has carried out the work "In pursuit of personal fame and happiness, with self-levied funds and deliberate evasion of supervision and private recruitment of related staff."
The authorities also believe that he falsified both ethical audit documents and blood tests to circumvent a ban on assisted reproduction for HIV-positive patients, reported state media.
Questions prompted the authenticity of his ethical approval documents shortly after the babies were revealed when one of the hospitals mentioned in the paperwork refused any involvement in the procedures.
Editing of the genes of embryos intended for pregnancy is prohibited in many countries, including the United States. In the UK, embryonic editing may be permitted for research purposes with strict approvals. It is unknown whether the procedure is safe or, if used during pregnancy, whether it can have undesirable consequences for the babies later in life or in future generations.
& # 39; A number of bad decisions & # 39;
After the first results of the study reported by Xinhua, Yalda Jamshidi, reading in genomic medicine at St. George's, the University of London, said the Chinese investigators seemed to confirm that the birth of the redesigned twins was the result of "a series of poor decisions."
"Surprisingly, the experiments have been met Critically criticized, especially as the procedures used have not been tested for human safety and were not performed for any real medical need, "Jamshidi said in an e-mail statement.  "The report will hopefully set an example of appropriate legal and punitive measures to reassure the public and scientific community that re-editing as all potentially new medical interventions will only be allowed when addressing a genuine medical need and with appropriate ethical and regulatory supervision ", the statement added.
But Dr. Helen O'Neill, Neill, reproductive science program and women's health at University College London, had a more subdued response to recent outcomes.
"Reports do not throw much in the way of new light on history. There is no further clarification as to what measures need to be taken to prevent this in the future or what will be done as punishment for Han Jiankui lacking in policy , patients and science. "
Authorities in China said he and all other people or institutions involved will be" treated seriously in accordance with the law, and if they are suspected of crimes, they will be transferred to the public security agency, " according to Xinhua.
"For the born babies and pregnant volunteers, Guangdong Province will cooperate with relevant parties to carry out medical observation and follow-up visits under the direction of the relevant state de partments," said Xinhua, adding that born babies and pregnant volunteers will be monitored and followed up with under the guidance of relevant government departments.
