    UK Considers Request From Scientists to Edit Embryo Genes

    An application to edit genes in human embryos is being considered by the Human Fertilization and Embryology Authority (HFEA) in the UK. If given the go-ahead, the request would be the world’s first ever approval by a national regulatory body to edit embryonic genes.

    A team of scientists in London, led by Dr Kathy Niakan has made the request. The researcher said her team wanted to use gene editing to provide "fundamental insights into early human development". 

    Genetically modifying embryos to eradicate diseases is currently illegal in the UK – but it remains possible to explore this biological field under a licence from the HFEA and using a technology called CRISPR/Cas9 which is a technique that can precisely target DNA and modify it.

    CRISPR/Cas9 technology has rapidly developed in the last three years and now researchers are keen to see how it can be used in humans in the future.

    Dr Kathy Niakan and her team of scientists from London’s Francis Crick Institute told the Guardian that they would like to use the technology to switch genes on and off in embryos in their developmental stage. They would then examine what effect this has on cells in the placenta.

    Essentially, using the research to see why some women experience multiple miscarriages. 

    "By applying more precise and efficient methods in our research we hope to require fewer embryos and be more successful than the other methods currently used," Dr Niakan said.

    Under UK law, embryos can only be studied for up to two weeks. In this research experiment, scientists would only use embryos donated from people undergoing IVF.

    "It is essential to study the function of these human genes in the context of the embryo in order to fully understand their roles," Niakan told the Guardian.

    However, it emerged in April that a Chinese team of scientists had already used the CRISPR/Cas9 technique to genetically engineer human embryos, prompting a debate among ethicists, scientists and policy makers as to how far this research should go.

    Ewan Birney of the European Bioinformatics Institute told the Independent:

    "I am concerned by this study. Using the gene-editing technology CRISPR/Cas9 in human embryos is unacceptable in the UK ethical framework."

    The HFEA has confirmed it has received the application for gene-editing under a license using CRISPR/Cas9 and "it will be considered in due course". If given the go-ahead, the UK’s genetic experiment on embryos would be a world first of such research by a regulatory body, potentially paving the way for many more.
