    en.wikipedia.org/wiki/Single-nucleotide_polymorphism

    A SNP in the F5 gene causes Factor V Leiden thrombophilia. [50] rs3091244 is an example of a triallelic SNP in the CRP gene on human chromosome 1. [51] TAS2R38 codes for PTC tasting ability, and contains 6 annotated SNPs. [52] rs148649884 and rs138055828 in the FCN1 gene encoding M-ficolin crippled the ligand-binding capability of the ...

  3. Common disease-common variant - Wikipedia

    en.wikipedia.org/wiki/Common_disease-common_variant

    SNP variants tend to be common in different human populations. These polymorphisms have been valuable as genomic signposts, or "markers", in the search for common variants that influence susceptibility to common diseases. Research has linked common SNPs to diseases such as type 2 diabetes, Alzheimer's, schizophrenia and hypertension. [2] [3] [4 ...

  4. Genome-wide association study - Wikipedia

    en.wikipedia.org/wiki/Genome-wide_association_study

    As of 2009, SNPs associated with diseases are numbered in the thousands. [34] The first GWA study, conducted in 2005, compared 96 patients with age-related macular degeneration (ARMD) with 50 healthy controls. [35] It identified two SNPs with significantly altered allele frequency between the two groups.

  5. SNP genotyping - Wikipedia

    en.wikipedia.org/wiki/SNP_genotyping

    SNPs are one of the most common types of genetic variation. An SNP is a single base pair mutation at a specific locus, usually consisting of two alleles (where the rare allele frequency is > 1%). SNPs are found to be involved in the etiology of many human diseases and are becoming of particular interest in pharmacogenetics.

  6. Disease gene identification - Wikipedia

    en.wikipedia.org/wiki/Disease_gene_identification

    Disease gene identification is a process by which scientists identify the mutant genotypes responsible for an inherited genetic disorder. Mutations in these genes can include single nucleotide substitutions, single nucleotide additions/deletions, deletion of the entire gene, and other genetic abnormalities.

  7. 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.

  8. Gene desert - Wikipedia

    en.wikipedia.org/wiki/Gene_desert

    Another affected region in the 9p21 gene desert causes several coronary artery diseases. [16] However, none of these risk-conferring gene deserts seem to be affected as much as the 8q24 regions. Current studies are still unsure about the SNP-affected processes in the 8q24 region that result in particularly amplified responses to the MYC promoter.

  9. Genetic causes of type 2 diabetes - Wikipedia

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

    Another example of faulty gene regulation that influence the susceptibility is the SNPs in promoter regions of the genes. Gene like APOM and APM1 increase the risk of type 2 diabetes when there are SNPs in their proximal promoter regions. Promoters are sequences of DNA that allows proteins such as transcription factors to bind for gene ...
