Study: X-chromosome mutation associated with CRC

A mutation on the X chromosome may cause colorectal cancer by inhibiting the SHROOM2 gene, which plays a role in cell development, according to a study published in Nature Genetics. Researchers said the finding could explain why the disease is more prevalent in men than women. The researchers also linked mutations in a gene involved in tumor suppression and a DNA repair gene to colorectal cancer. Google/The Press Association (U.K.) (5/28)
