About: HHaA

An Entity of Type: protein, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

HHaA is a human pseudogene believed to be responsible for fur-like body hair. In humans the gene has become deactivated making it a pseudogene, however there is variation in the degree of body hair among human beings and occasional examples have been found of people where the gene is active leading to very thick body hair as a result. Although the mutation was dated to 240 000 by Winter et al., it is also present in the Vindija Neandertal and Altai Denisovan sequences. Hence the dating must be older than 700 00 kya and possibly more than 1 mya considering the latter's divergence date. Given the divergence of pubic and head hair lice, the date of the mutation may be as old as 3.3 million years old.

  • HHaA is a human pseudogene believed to be responsible for fur-like body hair. In humans the gene has become deactivated making it a pseudogene, however there is variation in the degree of body hair among human beings and occasional examples have been found of people where the gene is active leading to very thick body hair as a result. Although the mutation was dated to 240 000 by Winter et al., it is also present in the Vindija Neandertal and Altai Denisovan sequences. Hence the dating must be older than 700 00 kya and possibly more than 1 mya considering the latter's divergence date. Given the divergence of pubic and head hair lice, the date of the mutation may be as old as 3.3 million years old. (en)
  • HHaA é um pseudogene humano que se acredita ser responsável pelos pelos do corpo, semelhantes a peles. Nos seres humanos, o gene foi desativado, tornando-o um pseudogene, no entanto, há variação no grau de pelos corporais entre seres humanos e exemplos ocasionais foram encontrados em pessoas onde o gene é ativo, resultando em cabelos corporais muito espessos. Embora a mutação tenha sido datada para 240000 por Winter et al., ela também está presente nas sequências de Vindija Neandertal e Altai Denisovan. Portanto, a data deve ter mais de 700000 anos e possivelmente mais de um milhão de anos, considerando a data de divergência deste último. Dada a divergência dos piolhos pubianos e dos pelos da cabeça, a data da mutação pode ser tão antiga quanto 3,3 milhões de anos. (pt)
