Tissue typing

A test carried out to determine what combination of a particular set of genetic markers (termed HLA markers) a person has inherited. This procedure can be carried out on IVF embryos, to establish potential tissue compatibility for donating umbilical cord blood to a sibling.

Licensing 'saviour siblings': Why the HFEA is right

22 February 2010 - by Dr Malcolm Smith

Two recent Bionews commentaries have considered the Human Fertilisation and Embryology Authority's (HFEA) review of the case-case approach to licensing PGD (preimplantation genetic diagnosis) for late-onset disorders and the use of pre-implantation tissue-typing (PITT) for the creation of 'saviour siblings'. This article considers further, some of the underlying reasons why the HFEA approach to case-by-case licensing of PITT is justified.... [Read More]

'Embryo destroyed' stories came from nowhere

01 February 2010 - by Dr Vivienne Raper

Newspaper stories claiming that fertility regulators in the UK have allowed embryos to be destroyed for 'minor disorders' are unrelated to decisions taken at a recent regulatory meeting. Stories last week said the Human Fertilisation and Embryology Authority (HFEA) had allowed doctors to routinely screen out more than 100 genetic disorders using PGD (preimplantation genetic diagnosis). But, according to HFEA sources, the list of genetic disorders approved for PGD... [Read More]

The case for case-by-case regulation of PGD: a response to Dr David King

26 January 2010 - by Nick Meade

The Genetic Interest Group (GIG) welcomed the UK's Human Fertilisation and Embryology Authority (HFEA)’s review of the case-by-case approach to the licensing of preimplantation genetic diagnosis (PGD) for late-onset conditions and for tissue typing of embryos to produce a 'saviour sibling'. I attended the HFEA's consultation event at which Dr David King spoke on 1 December last year and heard his presentation. Then, as in his BioNews comment

The case for case-by-case regulation of PGD

18 January 2010 - by Dr David King

On 20 January, the UK's Human Fertilisation and Embryology Authority (HFEA) will decide whether to continue the case-by-case regulation of two types of preimplantation genetic diagnosis (PGD) applications: those for late onset conditions and tissue typing of embryos to produce a 'saviour sibling'....

Twin saviour siblings born in the UK

17 August 2009 - by Ailsa Stevens

Twins born following IVF treatment to select embryos which would be a tissue match for their elder brother are thought to be the first incidence in the UK of multiple 'saviour siblings'. Out of just twelve licences granted by the Human Fertilisation and Embryology Authroity (HFEA) to permit families to create a saviour sibling, only this one has resulted in twins.... [Read More]

'My Sister's Keeper' is based on a book by the author Jodi Picoult. The youngest daughter of the Fitzgerald family, Anna (Abigail Breslin), decides to sue her parents for the ‘medical emancipation’ of her own body. Having been conceived through IVF and the resulting embryo tissue typed to ensure it was a match for her sick existing sibling, Anna was born for the primary reason of keeping her older sister, Kate (Sofia Vassilieva), a leukaemia patient, alive....

New method to multiply stem cells may help bone marrow transplants

20 April 2009 - by Dr Rebecca Robey

UK Parliament legislates 'saviour sibling' treatment

27 May 2008 - by MacKenna Roberts

UK MPs have rejected amendments that sought to outlaw the creation of 'saviour siblings'- babies conceived following embryo testing to ensure their cord blood will provide tissue-matched stem cells for an existing sick child. The controversial clause, contained within the Human Fertilisation and Embryology Bill before the... [Read More]

Scientists, hybrid embryos and the media

28 April 2008 - by Fiona Fox

Should scientists enter the media fray on the most controversial aspects of stem cell research when the row is clearly about much more than the science? This is a question that many in the scientific community have raised over the past year in relation to the furore over human-animal hybrid... [Read More]

Regulating IVF and embryo research: Balancing clarity with flexibility

19 July 2007 - by James Lawford Davies

I will miss the UK's Human Fertilisation and Embryology (HFE) 1990 Act when it is gone. I am no great supporter of our regulatory model and the 1990 Act is flawed and idiosyncratic. However, if you are going to regulate IVF and embryo research, ours is a reasonably solid regulatory... [Read More]
