Why some people have kidney stones



     A new study has provided evidence to explain why some people are more prone to developing kidney stones than others. Scientists at Washington University School of Medicine in St Louis found that other than diet (not drinking enough water) genes are to blame as well. A common genetic variation in a gene called claudin-14 recently has been linked to a substantial increase in risk — roughly 65% — of getting kidney stones. The researchers have shown how alterations in the gene’s activity influence the development of stones.
