It’s estimated that one in 300-400 people in the general population carry a mutation in either of these genes. Among people of Ashkenazi (Eastern European) Jewish descent, the prevalence is … Read more
A relatively small proportion of breast cancers are caused by alterations in inherited genes that sharply increase the lifetime risk of developing breast cancer. One of these genes has recently been receiving new attention: PALB2, a potent breast cancer susceptibility gene related to the better-known BRCA1 and BRCA2 genes. Someone who inherits a PALB2 mutation faces … Read more
What is the BRCA gene? BRCA1 and BRCA2 play a big role in preventing cancer. They belong to a class of genes called tumor suppressors, which ensure that breast, ovarian, and other types of cells don’t grow or divide too rapidly or uncontrollably. BRCA testing checks for mutations in either gene, and can help people decide … Read more
