Associated Genetic Biomarkers
GNA11 (guanine nucleotide binding protein (G protein), alpha 11 (Gq class)) is a gene that encodes the guanine nucleotide-binding protein subunit alpha-11, a subunit of one of the heterotrimeric guanine nucleotide binding proteins (G proteins). Oncogenic mutations result in a constitutively active Gα subunit (PMID: 1328859; PMID: 2549426). Receptor activation causes the dissociation of the Gα subunit from Gßγ. Both Gα and Gßγ can then activate downstream cellular signaling pathways (PMID: 1328859; PMID: 2549426).
GNA11 is altered in 0.67% of all cancers with uveal melanoma, colon adenocarcinoma, lung adenocarcinoma, breast invasive ductal carcinoma, and high grade ovarian serous adenocarcinoma having the greatest prevalence of alterations .
The most common alterations in GNA11 are GNA11 Mutation (0.72%), GNA11 Loss (0.16%), GNA11 Q209L (0.13%), GNA11 Amplification (0.05%), and GNA11 R183C (0.02%) .
GNA11 status serves as an inclusion eligibility criteria in 2 clinical trials, of which 2 are open and 0 are closed. Of the trials that contain GNA11 status as an inclusion criterion, 1 is phase 1 (1 open) and 1 is phase 1/phase 2 (1 open).
Trials with GNA11 status in the inclusion eligibility criteria most commonly target colorectal carcinoma, cutaneous melanoma, malignant solid tumor, melanoma, and uveal melanoma .
The most frequent alteration to serve as an inclusion eligibility criterion is GNA11 Mutation .
Ide196, ipilimumab, nivolumab, and pegargiminase are the most frequent therapies in trials with GNA11 as an inclusion criteria .
Significance of GNA11 in Diseases
Uveal Melanoma +
GNA11 is altered in 31.36% of uveal melanoma patients .
GNA11 is an inclusion criterion in 2 clinical trials for uveal melanoma, of which 2 are open and 0 are closed. Of the trials that contain GNA11 status and uveal melanoma as inclusion criteria, 1 is phase 1 (1 open) and 1 is phase 1/phase 2 (1 open) .
Cutaneous Melanoma +
Colorectal Carcinoma +
GNA11 is altered in 0.65% of colorectal carcinoma patients .
GNA11 is an inclusion criterion in 1 clinical trial for colorectal carcinoma, of which 1 is open and 0 are closed. Of the trial that contains GNA11 status and colorectal carcinoma as inclusion criteria, 1 is phase 1/phase 2 (1 open) .
Malignant Solid Tumor +
GNA11 is altered in 0.69% of malignant solid tumor patients .
GNA11 is an inclusion criterion in 1 clinical trial for malignant solid tumor, of which 1 is open and 0 are closed. Of the trial that contains GNA11 status and malignant solid tumor as inclusion criteria, 1 is phase 1/phase 2 (1 open) .
