This genome-wide association study analyzed the genetic data of 95,380 Japanese men to better understand the genetic factors that contribute to this condition. The study discovered 46 genetic variants of which 35 are novel, and collectively these variants explain an estimated 9% of the heritability of mLOY. Many of the identified genetic variants are near genes that are active in blood stem cells.<\/p>\n\n\n\n<p><strong>DID YOU KNOW?<\/strong> Studies have shown that smoking may significantly increase the risk of mosaic loss of chromosome Y. There is good news for smokers looking to quit \u2013 the same research showed that previous smokers were not any more likely to have Y chromosome loss than never smokers.
