Researchers have shown that cancer susceptibility in BRCA1/2 occurs at disproportional rates and statistical degrees across a wide range of species, particularly non-human primates. This study incorporates two primary scopes for examining BRCA 1/2 cancer susceptibility among closely related lineages: (1) phylogenetic reconstruction of mRNA BRCA1/2 genes (both cancer susceptible and non-cancer susceptible) in variously distinct primate families (including Homo sapiens); and (2) pairwise comparative analysis of breast cancer 1 early onset BRCA1 mRNA partial cds within immediate human populations. The results generated by phylogenetic reconstruction together with pairwise comparative analysis revealed that cancer-causing alterations in BRCA1/2 appear to originate within localized gene pools at separate junctures throughout evolutionary time. This supports the explanation that BRCA1/2 genes may be undergoing rapid evolution, as revealed by unusually high proportion of dissimilarities between cancer susceptibility sequences among members of each group or species.
