The most important BRAF mutation in ovarian cancer leads to increased kinase activity, the p. V600E mutation.
CTNNB1: 9 Assays
The most frequently detected CTNNB1/beta-catenin mutations result in abnormal signaling in the WNT signaling pathway. The mutated codons are mainly several serine/threonine residues targeted for phosphorylation by GSK-3beta.
ERBB2: 2 Assays
The most frequently identified ERBB2 activating mutations cluster in the ERBB2 kinase domain region.
FOXL2: 1 Assay
This mutation lies in wing 2 of the forkhead domain, a divergent component of the domain's secondary structure with unknown function, but the mutation does seem to inhibit the protein's pro-apoptotic function.
GNAS: 1 Assay
Mutations in this gene result in pseudohypoparathyroidism type 1a (PHP1a), which has an atypical autosomal dominant inheritance pattern requiring maternal transmission for full penetrance.
KIT: 3 Assays
The most frequently identified KIT gain-of-function mutations include the D816V point mutation, the exon 11 (juxtamembrane domain) deletion and point mutations, an exon 9 insertion mutation, and exon 13 point mutations.
KRAS: 10 Assays
The mutation assays include the most frequently occurring mutations in KRAS codons 12, 13, and 61. Mutations at these positions result in reduced intrinsic GTPase activity and/or cause KRAS to become unresponsive to RasGAP.
NRAS: 1 Assay
The most important NRAS mutation in ovarian cancer occurs at codon 12.
PIK3CA: 7 Assays
The most frequently occurring PIK3CA mutations mainly belong to two classes: gain-of-function kinase domain activating mutations and helical domain mutations that mimic activation by growth factors.
PTEN: 3 Assays
The most commonly detected PTEN loss-of-function mutations are due to either truncation (p.R233* and p.R130*) or point mutations causing phosphatase inactivation (p.R130 and p.R173 mutations).
TP53: 45 Assays
The most frequently detected somatic mutations in TP53 are largely composed of DNA-binding domain mutations which disrupt either DNA binding or protein structure.
