Genetics of population isolates

Arcos‐Burgos, M, Muenke, M·2002·Clinical Genetics

Abstract

Genetic isolates, as shown empirically by the Finnish, Old Order Amish, Hutterites, Sardinian and Jewish communities among others, represent a most important and powerful tool in genetically mapping inherited disorders. The main features associated with that genetic power are the existence of multigenerational pedigrees which are mostly descended from a small number of founders a short number of generations ago, environmental and phenotypic homogeneity, restricted geographical distribution, the presence of exhaustive and detailed records correlating individuals in very well ascertained pedigrees, and inbreeding as a norm. On the other hand, the presence of a multifounder effect or admixture among divergent populations in the founder time (e.g. the Finnish and the Paisa community from Colombia) will theoretically result in increased linkage disequilibrium among adjacent loci. The present review evaluates the historical context and features of some genetic isolates with emphasis on the basic population genetic concepts of inbreeding and genetic drift, and also the state‐of‐the‐art in mapping traits, both Mendelian and complex, on genetic isolates.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The community in the metropolitan area of Medellin shares the same genetic background and genealogy as the population with the E280A mutation.

    “Although these individuals do not carry the PSEN1 E280A mutation, several population genetic analyses have shown that the community inhabiting this area has not been subject to microdifferentiation and shares the same genetic background and genealogy as the population with the E280A mutation.2, 3”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
