About This Section

Entrez Gene summary for KRAS Gene:
This gene, a Kirsten ras oncogene homolog from the mammalian ras gene family, encodes a protein that is a member
of the small GTPase superfamily. A single amino acid substitution is responsible for an activating mutation. The
transforming protein that results is implicated in various malignancies, including lung adenocarcinoma, mucinous
adenoma, ductal carcinoma of the pancreas and colorectal carcinoma. Alternative splicing leads to variants
encoding two isoforms that differ in the C-terminal region. (provided by RefSeq, Jul 2008)

GeneCards Summary for KRAS Gene: 
KRAS (Kirsten rat sarcoma viral oncogene homolog) is a protein-coding gene. Diseases associated with KRAS include lung adenocarcinoma, and cronkhite-canada syndrome, and among its related super-pathways are ErbB signaling pathway and Glioma. GO annotations related to this gene include GDP binding and GTP binding. An important paralog of this gene is RAP2C.

UniProtKB/Swiss-Prot: RASK_HUMAN, P01116
Function: Ras proteins bind GDP/GTP and possess intrinsic GTPase activity

  • Leukemia, acute myelogenous (AML) [MIM:601626]: A subtype of acute leukemia, a cancer of the white blood
    cells. AML is a malignant disease of bone marrow characterized by maturational arrest of hematopoietic precursors
    at an early stage of development. Clonal expansion of myeloid blasts occurs in bone marrow, blood, and other
    tissue. Myelogenous leukemias develop from changes in cells that normally produce neutrophils, basophils,
    eosinophils and monocytes. Note=The disease is caused by mutations affecting the gene represented in this entry
  • Leukemia, juvenile myelomonocytic (JMML) [MIM:607785]: An aggressive pediatric myelodysplastic
    syndrome/myeloproliferative disorder characterized by malignant transformation in the hematopoietic stem cell
    compartment with proliferation of differentiated progeny. Patients have splenomegaly, enlarged lymph nodes,
    rashes, and hemorrhages. Note=The disease is caused by mutations affecting the gene represented in this entry
  • Noonan syndrome 3 (NS3) [MIM:609942]: A syndrome characterized by facial dysmorphic features such as
    hypertelorism, a downward eyeslant and low-set posteriorly rotated ears. Other features can include short
    stature, a short neck with webbing or redundancy of skin, cardiac anomalies, deafness, motor delay and variable
    intellectual deficits. Note=The disease is caused by mutations affecting the gene represented in this entry
  • Gastric cancer (GASC) [MIM:613659]: A malignant disease which starts in the stomach, can spread to the
    esophagus or the small intestine, and can extend through the stomach wall to nearby lymph nodes and organs. It
    also can metastasize to other parts of the body. The term gastric cancer or gastric carcinoma refers to
    adenocarcinoma of the stomach that accounts for most of all gastric malignant tumors. Two main histologic types
    are recognized, diffuse type and intestinal type carcinomas. Diffuse tumors are poorly differentiated
    infiltrating lesions, resulting in thickening of the stomach. In contrast, intestinal tumors are usually
    exophytic, often ulcerating, and associated with intestinal metaplasia of the stomach, most often observed in
    sporadic disease. Note=The disease is caused by mutations affecting the gene represented in this entry
  • Note=Defects in KRAS are a cause of pylocytic astrocytoma (PA). Pylocytic astrocytomas are neoplasms of
    the brain and spinal cord derived from glial cells which vary from histologically benign forms to highly
    anaplastic and malignant tumors
  • Cardiofaciocutaneous syndrome (CFC syndrome) [MIM:115150]: Characterized by a distinctive facial
    appearance, heart defects and mental retardation. Heart defects include pulmonic stenosis, atrial septal defects
    and hypertrophic cardiomyopathy. Some affected individuals present with ectodermal abnormalities such as sparse,
    friable hair, hyperkeratotic skin lesions and a generalized ichthyosis-like condition. Typical facial features
    are similar to Noonan syndrome. They include high forehead with bitemporal constriction, hypoplastic supraorbital
    ridges, downslanting palpebral fissures, a depressed nasal bridge, and posteriorly angulated ears with prominent
    helices. The inheritance of CFC syndrome is autosomal dominant. Note=The disease is caused by mutations affecting
    the gene represented in this entry
  • Note=KRAS mutations are involved in cancer development
