Abstract

The Chuvash form of polycythemia is an autosomal recessive disorder common to a large number of families in central Russia. Affected individuals have been reported to be homozygous for an Arg200Trp mutation in the von Hippel-Lindau (VHL) gene. We have screened 78 patients with erythrocytosis and found 8 of Bangladeshi and Pakistani origin to be homozygous for the Arg200Trp mutation and another of English descent to be heterozygous. Of these patients, 5 have elevated serum erythropoietin (Epo) levels, while the other 4 have Epo values in the normal range. The heterozygous patient does not fulfill the Chuvash criterion for homozygosity of the Arg200Trp mutation and consequently may harbor a further, as yet uncharacterized, mutation. This mutation has a wider geographic distribution than originally presumed and haplotype analysis suggests a common origin of the Arg200Trp mutation in the 4 families, but it still remains to be established if it has arisen independently of the Chuvash population.

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.
