    Summary
    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]

    Cardio-facio-cutaneous syndrome

    Summary from GeneReviews: Cardiofaciocutaneous Syndrome Go to GeneReviews

    Disease Characteristics
    Cardiofaciocutaneous (CFC) syndrome is characterized by cardiac abnormalities (pulmonic stenosis and other valve dysplasias, septal defects, hypertrophic cardiomyopathy, rhythm disturbances), distinctive craniofacial appearance, and cutaneous abnormalities (including xerosis, hyperkeratosis, ichthyosis, keratosis pilaris, ulerythema ophryogenes, eczema, pigmented moles, hemangiomas, and palmoplantar hyperkeratosis). The hair is typically sparse, curly, fine or thick, woolly or brittle; eyelashes and eyebrows may be absent or sparse. Nails may be dystrophic or fast growing. Some form of neurologic and/or cognitive delay (ranging from mild to severe) is seen in all affected individuals. Neoplasia, mostly acute lymphoblastic leukemia (ALL), has been reported in some individuals.
    Diagnosis Testing
    Diagnosis is based on clinical findings and molecular genetic testing. The four genes known to be associated with CFC syndrome are: BRAF (~75%), MAP2K1 and MAP2K2 (~25%), and KRAS (<2%). Molecular genetic testing is available clinically for all known genes.
    Genetic Counseling
    Cardiofaciocutaneous (CFC) syndrome is usually the result of a de novo dominant mutation. The risk to the sibs of a proband is small. To date, one family with transmission of an autosomal dominant germline mutation (MAP2K2) through multiple generations has been reported. Prenatal diagnosis for pregnancies at increased risk because of the theoretical possibility of germline mosaicism or for couples needing reassurance is possible if the disease-causing allele of the affected family member is known.

    Familial cancer of breast

    Summary from GeneReviews: BRCA1 and BRCA2 Hereditary Breast/Ovarian Cancer Go to GeneReviews

    Disease Characteristics
    A germline mutation in BRCA1 or BRCA2 predisposes to breast and ovarian cancer as well as other cancers. The risk of developing cancer that is associated with a germline BRCA1 or BRCA2 mutation, which has been derived from families with multiple affected individuals, families with few affected individuals, and from population-based studies, appears to be variable within families. Prognosis for breast and ovarian cancer depends on the stage at which the cancer is diagnosed; however, studies on survival have revealed conflicting results for individuals with germline BRCA1 or BRCA2 mutations when compared to controls.
    Diagnosis Testing
    Molecular genetic testing for germline BRCA1 and BRCA2 mutations is available on a clinical basis for individuals who are identified to be at high risk based on their personal and/or family history and for at-risk relatives of an individual with an identified germline BRCA1 or BRCA2 mutation. No currently available technique can guarantee the identification of all cancer-predisposing mutations in BRCA1 or BRCA2. Furthermore, mutations of uncertain clinical significance may be identified.
    Genetic Counseling
    Germline mutations in BRCA1 and BRCA2 are inherited in an autosomal dominant manner. Each offspring of an individual with a BRCA1 or BRCA2 germline mutation has a 50% chance of inheriting the mutation. Molecular genetic testing of asymptomatic family members at risk of inheriting either a BRCA1 or BRCA2 germline mutation is feasible once the family-specific mutation has been identified. Prenatal testing is possible for pregnancies at increased risk if the cancer-predisposing mutation in the family is known; however, requests for prenatal diagnosis of adult-onset diseases are uncommon and require careful genetic counseling.

    Hereditary diffuse gastric cancer

    Summary from GeneReviews: Hereditary Diffuse Gastric Cancer Go to GeneReviews

    Disease Characteristics
    Hereditary diffuse gastric cancer (HDGC) is autosomal dominant susceptibility for diffuse gastric cancer, a poorly differentiated adenocarcinoma that infiltrates into the stomach wall causing thickening of the wall (linitis plastica) without forming a distinct mass. Diffuse gastric cancer is also referred to as signet ring carcinoma or isolated cell-type carcinoma. The average age of onset of HDGC is 38 years, with a range of 14-69 years. The majority of the cancers in individuals with a CDH1 mutation occur before age 40 years. The estimated cumulative risk of gastric cancer by age 80 years is 80% for both men and women. Women also have a 39%-52% risk for lobular breast cancer.
    Diagnosis Testing
    The International Gastric Cancer Linkage Consortium defined HDGC as the presence of two or more documented cases of diffuse gastric cancer in first- or second-degree relatives with at least one case diagnosed prior to age 50 years OR three or more documented cases of diffuse gastric cancer in first- or second-degree relatives, regardless of age of onset. CDH1 is currently the only gene in which mutations are known to cause hereditary diffuse gastric cancer. Molecular genetic testing of CDH1 is available on a clinical basis.
    Genetic Counseling
    Hereditary diffuse gastric cancer is inherited in an autosomal dominant manner. The vast majority of individuals with a mutation predisposing to diffuse gastric cancer have inherited it from one parent. De novo mutations have not been reported. Each child of a proband has a 50% risk of inheriting the cancer-predisposing mutation. Prenatal testing for pregnancies at increased risk is possible if the disease-causing mutation in the family is known; however, requests for prenatal testing for conditions such as HDGC that do not affect intellect and have some treatment available are not common.

    Noonan syndrome 3

    Summary from GeneReviews: Noonan Syndrome Go to GeneReviews

    Disease Characteristics
    Noonan syndrome (NS) is characterized by short stature, congenital heart defect, and developmental delay of variable degree. Other findings can include broad or webbed neck, unusual chest shape with superior pectus carinatum and inferior pectus excavatum, cryptorchidism, characteristic facies, varied coagulation defects, lymphatic dysplasias, and ocular abnormalities. Although birth length is usually normal, final adult height approaches the lower limit of normal. Congenital heart disease occurs in 50%-80% of individuals. Pulmonary valve stenosis, often with dysplasia, is the most common heart defect and is found in 20%-50% of individuals. Hypertrophic cardiomyopathy, found in 20%-30% of individuals, may be present at birth or develop in infancy or childhood. Other structural defects include atrial and ventricular septal defects, branch pulmonary artery stenosis, and tetralogy of Fallot. Up to one third of affected individuals have mild intellectual disability.
    Diagnosis Testing
    NS is diagnosed on clinical grounds by observation of key features. Affected individuals have normal chromosome studies. Molecular genetic testing identifies a mutation in PTPN11 in 50% of affected individuals, SOS1 in approximately 13%, RAF1 in 3% to 17%, and KRAS in fewer than 5%. Other genes in which mutations have been reported to cause Noonan syndrome in fewer than 1% of cases include NRAS, BRAF, and MAP2K1.
    Genetic Counseling
    NS is inherited in an autosomal dominant manner. Although many individuals with NS have a de novo mutation, an affected parent is recognized in 30%-75% of families. The risk to sibs of a proband depends on the genetic status of the parents. If a parent is affected, the risk is 50%. When the parents are clinically unaffected, the risk to the sibs of a proband appears to be low (<1%). Each child of an individual with Noonan syndrome has a 50% chance of inheriting the mutation. Prenatal testing is possible if the disease-causing allele has been identified in an affected family member.

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

        Links between Gene and PubMed are the result of the following: 1. Manual curation within NCBI. Part of the process of generating a REVIEWED RefSeq is an analysis of the current literature. Papers that are seminal in defining the gene, its sequence, and its function are added to the record at that time. Alert users point out gaps or errors in papers associated with a Gene record. These messages are reviewed and implemented as required. 2. Integration of information from other public databases. Gene integrates gene-citation from resources external to NCBI such as model organism-specific databases, Gene Ontology (GO), groups curating interactions, and sequence databases. The assumption in using these source is that they report citations specific to a gene in a known species. Gene does not process citations from OMIM automatically, because many of citations in OMIM refer to studies of genes in species other than human.
      • PubMed (GeneRIF)
        GeneRIF -- Gene Reference Into Function Staff of the Index Section in the National Library of Medicine review the current literature. When they find articles focused on the structure and function of a gene, they write a brief summary of the impact of the paper and make the connection between the citation (PubMed) and Gene. An interface exists for interested users to submit such data as well. http://www.ncbi.nlm.nih.gov/projects/GeneRIF/GeneRIFhelp.html
