Genes affected
NRAS (HGNC:7989): (NRAS proto-oncogene, GTPase) This is an N-ras oncogene encoding a membrane protein that shuttles between the Golgi apparatus and the plasma membrane. This shuttling is regulated through palmitoylation and depalmitoylation by the ZDHHC9-GOLGA7 complex. The encoded protein, which has intrinsic GTPase activity, is activated by a guanine nucleotide-exchange factor and inactivated by a GTPase activating protein. Mutations in this gene have been associated with somatic rectal cancer, follicular thyroid cancer, autoimmune lymphoproliferative syndrome, Noonan syndrome, and juvenile myelomonocytic leukemia.

ACMG classification

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 9 ACMG points.

PM1
In a chain GTPase NRas (size 185) in uniprot entity RASN_HUMAN there are 29 pathogenic changes around while only 3 benign (91%) in NM_002524.5
PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 30 curated pathogenic missense variants (we use a threshold of 10). The gene has 1 curated benign missense variants. Gene score misZ: 1.7139 (below the threshold of 3.09). Trascript score misZ: 2.2391 (below the threshold of 3.09). GenCC associations: The gene is linked to cardiofaciocutaneous syndrome, Noonan syndrome, Noonan syndrome 6, Costello syndrome, Noonan syndrome with multiple lentigines.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.981
