It has been informed recently that a group of scientists has identified mutated genes in humans that hold the potential of causing stroke. It is estimated that every year, six million people succumbs to death after being affected with stroke, all over the world.

Stroke has been regarded as second top cause of mortality in the developed countries. It is believed that the findings of the researchers would help in paving way for better diagnosis and effective treatment of patients.

In countries like Britain and Germany, blocked vessels have been found to be one of the main reasons behind causing brain stroke. Moreover, mutated genes known as HDAC9 also have been criticized for causing stroke. For long, it was known that stroke occurs due to family history, it is for the very first time when the faulty DNA has been identified by the scientists.

For long, scientists believed that the mutated genes HDAC9 are required in the development of muscle tissue and heart. However, little was known that the variation of the same gene could also be responsible for triggering stroke. It has been informed that these particular genes lead to large-artery ischaemic stroke.

It has been informed by the scientists that about 10% of the chromosomes carry mutated version of HDAC9. Person who has got two variations of the HDAC9, which means one from his mother and the other from his father, has double risk of being affected with stroke.

The findings have been published in the Nature Genetics. The research was funded by the Wellcome Trust charity. For the research, the researchers used the advanced scientific technique for comparing the DNA of 10,000 patients who have experienced stroke with other 40,000 people, who have not experienced stroke.
