    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.

    The mutation in CCR5 is also quite common in certain areas, with more than 14% of the population carry the mutation in Europe and about 6–10% in Asia and North Africa. [99] HIV attachment. Apart from mutations, many genes that may have aided humans in ancient times plague humans today.

  4. Human Y-chromosome DNA haplogroup - Wikipedia

    en.wikipedia.org/wiki/Human_Y-chromosome_DNA_ha...

    The Y-chromosome accumulates approximately two mutations per generation, [3] and Y-DNA haplogroups represent significant branches of the Y-chromosome phylogenetic tree, each characterized by hundreds or even thousands of unique mutations. The Y-chromosomal most recent common ancestor (Y-MRCA), often referred to as Y-chromosomal Adam, is the ...

    en.wikipedia.org/wiki/Mitochondrial_Eve

    In human genetics, the Mitochondrial Eve (more technically known as the Mitochondrial-Most Recent Common Ancestor, shortened to mt-Eve or mt-MRCA) is the matrilineal most recent common ancestor (MRCA) of all living humans. In other words, she is defined as the most recent woman from whom all living humans descend in an unbroken line purely ...

  6. Genetic disorder - Wikipedia

    It can be caused by a mutation in a single gene (monogenic) or multiple genes (polygenic) or by a chromosome abnormality. Although polygenic disorders are the most common, the term is mostly used when discussing disorders with a single genetic cause, either in a gene or chromosome.

  7. Mutation - Wikipedia

    en.wikipedia.org/wiki/Mutation

    The typical human genome also contains 40,000 to 200,000 rare variants observed in less than 0.5% of the population that can only have occurred from at least one de novo germline mutation in the history of human evolution. [142] De novo mutations have also been researched as playing a crucial role in the persistence of genetic disease in humans.

  8. Recent human evolution - Wikipedia

    en.wikipedia.org/wiki/Recent_human_evolution

    While humans today carry far more mutations than their ancestors did 5,000 years ago, they are not necessarily more vulnerable to illnesses because these might be caused by multiple mutations. It does, however, confirm earlier research suggesting that common diseases are not caused by common gene variants. [ 90 ]

  9. Human genetics - Wikipedia

    en.wikipedia.org/wiki/Human_genetics

    Human genetics encompasses a variety of overlapping fields including: classical genetics, cytogenetics, molecular genetics, biochemical genetics, genomics, population genetics, developmental genetics, clinical genetics, and genetic counseling. Genes are the common factor of the qualities of most human-inherited traits.
