Premature birth gene 'discovered'

In this article, there was a discovery made that there is a gene  linked to premature births. Researchers at Vanderbilt University, Washington University and the University of Helsinki suspected that there was some evolutionary pressure to  "adapt and shift the time of birth" to produce smaller babies. The researchers looked for DNA which showed evidence of "accelerated evolution". These are the genes which have mutated more in humans than in other primates and have identified 150 genes. For the research to go on the next step was to look for an association with premature births. What the researchers did was that compared 150 genes in 328 Finnish mothers, some whom had premature births. There was a strong relation to pre-term births with variants of the FSHR - or follicle stimulating hormone receptor - gene. The follicle  stimulating hormone acts a s a recptor in the ovaries to encourage follicle (a sphere of cells containing an egg).  development and production of the hormone oestrogen.

This study is very early in its stages and needs to become experiments and tested more until their can be conclusive evidence. This is because when scientist find a relation between two variable it is more deeper than those to variables.
