  2. Mutation - Wikipedia

    en.wikipedia.org/wiki/Mutation

    Mutations can involve the duplication of large sections of DNA, usually through genetic recombination. [10] These duplications are a major source of raw material for evolving new genes, with tens to hundreds of genes duplicated in animal genomes every million years. [11] Most genes belong to larger gene families of shared ancestry, detectable ...

  3. List of genetic disorders - Wikipedia

    en.wikipedia.org/wiki/List_of_genetic_disorders

    The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child. There are over 6,000 known genetic disorders in humans.

  4. BRCA mutation - Wikipedia

    en.wikipedia.org/wiki/BRCA_mutation

    Medical genetics. A BRCA mutation is a mutation in either of the BRCA1 and BRCA2 genes, which are tumour suppressor genes. Hundreds of different types of mutations in these genes have been identified, some of which have been determined to be harmful, while others have no proven impact.

  5. Genetic variation - Wikipedia

    en.wikipedia.org/wiki/Genetic_variation

    Genetic variation is the difference in DNA among individuals [1] or the differences between populations among the same species. [2] The multiple sources of genetic variation include mutation and genetic recombination. [3] Mutations are the ultimate sources of genetic variation, but other mechanisms, such as genetic drift, contribute to it, as well.

  6. Causes of cancer - Wikipedia

    en.wikipedia.org/wiki/Causes_of_cancer

    Cancer is caused by genetic changes leading to uncontrolled cell growth and tumor formation. The basic cause of sporadic (non-familial) cancers is DNA damage and genomic instability. [1][2] A minority of cancers are due to inherited genetic mutations. [3] Most cancers are related to environmental, lifestyle, or behavioral exposures. [4]

  7. Gene duplication - Wikipedia

    en.wikipedia.org/wiki/Gene_duplication

    Gene duplications are an essential source of genetic novelty that can lead to evolutionary innovation. Duplication creates genetic redundancy, where the second copy of the gene is often free from selective pressure —that is, mutations of it have no deleterious effects to its host organism. If one copy of a gene experiences a mutation that ...

  8. Germline mutation - Wikipedia

    en.wikipedia.org/wiki/Germline_mutation

    Huntington's disease is an autosomal dominant mutation in the HTT gene. The disorder causes degradation in the brain, resulting in uncontrollable movements and behavior. [17] The mutation involves an expansion of repeats in the Huntington protein, causing it to increase in size. Patients who have more than 40 repeats will most likely be affected.

  9. Genetic causes of type 2 diabetes - Wikipedia

    en.wikipedia.org/wiki/Genetic_causes_of_type_2...

    Polygenic. Genetic cause and mechanism of type 2 diabetes is largely unknown. However, single nucleotide polymorphism (SNP) is one of many mechanisms that leads to increased risk for type 2 diabetes. To locate genes and loci that are responsible for the risk of type 2 diabetes, genome wide association studies (GWAS) was utilized to compare the ...
