They appear to be still working on it... So far, six potential prostate cancer genes are reported in the literature. All but HPC2 are yet to be isolated, and they probably are responsible for only a relatively small proportion of affected individuals in the general population. The disease is very complex due to the existence of more than one gene and decreased penetrance. (Penetrance is the probability that an individual carrying a disease gene is affected. Sometimes an individual who carries a gene for prostate cancer may not show symptoms). Moreover, sporadic and hereditary cases may co-exist in some families. Thus far, genetic research studies to identify genes have been performed on Caucasian Americans. Interestingly, confirmatory studies have usually failed to find the suggested genes in a different population. A large number of families from different populations with family histories of multiple affected prostate cancer cases are needed to confirm suggested genes and to find any new gene that may exist in the population.
