Summary (CIViC Variant)
PIK3CA H1047R is one of the most recurrent single nucleotide variants in cancer, especially breast cancer. Of PIK3CA-mutant breast cancers, over half harbor this mutation. Meta-analyses have shown that patients harboring this mutation may have worse overall survival, but other studies have shown no difference between H1047R and other PIK3CA mutants from a prognostic standpoint. While very prevalent, targeted therapies for this particular mutation are still in early clinical trial phases.
