What's the difference between cognation and consanguinity?

Cognation


Definition:

  • (n.) Relationship by blood; descent from the same original; kindred.
  • (n.) Participation of the same nature.
  • (n.) That tie of consanguinity which exists between persons descended from the same mother; -- used in distinction from agnation.

  • (20) Comparison of the nucleotide and deduced amino acid sequence of this genome segment with cognate segments of isolates of BTV 1 from Australia and South Africa, and BTV 10 and BTV 17 from the United States, revealed homologies of 98%, 80%, 79%, and 79%, respectively, at the nucleotide level and 98%, 90%, 89%, and 90% identity, respectively, at the amino acid level.

Consanguinity


Definition:

  • (n.) The relation of persons by blood, in distinction from affinity or relation by marriage; blood relationship; as, lineal consanguinity; collateral consanguinity.

Example Sentences:

  • (1) Legislation governing adoption has attempted to make the adoptive family the equivalent of a consanguinal one, with varying degrees of success.
  • (2) Two strikingly similar brothers issued from consanguineous parents in the second degree present the following patterns of anomalies: retardation of growth, mental deficiency, ocular abnormalities, pectus excavatum and camptodactyly.
  • (3) Parental consanguinity suggests that an autosomal recessive mutation is the likely aetiology.
  • (4) Any patient with a fairly symmetrical 'quiet' eye disease, especially if congenital, should be suspected of having an hereditary disease--presumably due to a recessive gene, even if the parents are not consanguineous, but possibly due to a mutation which could prove dominant; a search of the literature in such cases is useful.
  • (5) Taking advantage of the availability of an archive of consanguineous marriages that gives accurate estimates of consanguinity in Italy, it has been possible to calculate the increase of first- and second-cousin marriages among 624 couples of cystic fibrosis (CF) parents over the general population.
  • (6) Consanguinity of the kindreds could not be established.
  • (7) In this case, lower fertility might be expected in consanguineous marriages, only because of a higher probability of homozygosis of deleterious genes.
  • (8) The differences between consanguineous and non-consanguineous marriages in terms of total foetal loss, perinatal, neonatal, postneonatl and infant mortality rates showed only marginal differences that attain statistical significance only because of the large sample size involved.

  • (10) Impaired IL-2 activity was found in 15 of the 29 consanguineous relatives.
  • (11) Parental consanguinity in those with genetically determined causes of visual impairment was high compared with those with nongenetic causes (79% vs 33.3%, P < .05).
