Phenotype-genotype relationships in monogenic disease: lessons from the thalassaemias

Weatherall, D. J.·2001·Nature Reviews Genetics

Abstract

The remarkable phenotypic diversity of the beta-thalassaemias reflects the heterogeneity of mutations at the beta-globin locus, the action of many secondary and tertiary modifiers, and a wide range of environmental factors. It is likely that phenotype-genotype relationships will be equally complex in the case of many monogenic diseases. These findings highlight the problems that might be encountered in defining the relationship between the genome and the environment in multifactorial disorders, in which the degree of heritability might be relatively low and several environmental agents are involved. They also emphasize the value of an understanding of phenotype-genotype relationships in designing approaches to gene therapy.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • Patients affected by sickle cell anemia and β-thalassemia experience a milder course of the disease if they express elevated levels of fetal hemoglobin in adulthood.

    “Patients affected by sickle cell anemia and β-thalassemia experience a milder course of the disease if they express elevated levels of fetal hemoglobin in adulthood (Platt et al., 1994; Weatherall, 2001).”

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.
