Genetics and miscarriage

Canadian researches have discovers the molecular glitch that explains why so many women lose their babies late in their pregnancy Known as foetal growth restriction , the condition strikes three percent of all pregnancies and is a leading cause of infant deaths. Earlier research had shown that a gene producing a protein known as insulin like growth factor 2 or igf 2 was critical to feed the foetus and help foetal cells divide and grow. The Canadian results showed that the normal form of this protein has a very long chemical structure. However, to function properly when helping to build the placenta, another molecule, PC4 has to effectively work like scissors and cut the growth factor protein to the length crucial to healthy pregnancy.
