Coinheritance of Chromosomes 3 and 11 in the Patients with Autosomal Recessive Polycythemia from Chuvachia

Abstract

Inheritance of chromosomes 3 and 11 in the families with Chuvash autosomal recessive polycythemia and in control group with no disease symptoms was examined using polymorphic dinucleotide markers D3S1597 and D3S1263 , mapped to region 3p25, and D11S4111 , D11S4127 , and D11S1356 , mapped to region 11q23. All patients were homozygous for the C598T mutation in the VHL gene (3p25). The analysis showed that in 75% of the cases, chromosome 3 carrying C598T mutation was coinherited with certain chromosome 11, which differed from 50%, expected upon independent inheritance of each chromosome. In case of chromosome 3 without C598T mutation, this pattern was observed neither in healthy sibs form the families with autosomal recessive polycythemia (44%), nor in the control group (43%). These results suggest that in case of the C598T mutation in the VHL gene, chromosomal loci 3p25 and 11q23 are inherited not independently, compared to the inheritance of these loci in the absence of the mutation in healthy sibs from the affected families ( χ 2 = 16.14,  < 0.001 ), and also in the control family sample ( χ 2 = 17.91, p < 0.001 ).

The gauge model of quark-meson interactions and the Higgs status of scalar mesons.

“…Totally, this multiplicative parameter increases the ratio no more than (8 − 10)%, due to the formfactors contribution. Curve (2) demonstrates comparison of the spectrum with the experimental data [12,13]. To describe the spectrum fine structure near E max , it was suggested to consider the loop corrections (see [14,15] we get the value of ρ-meson branching B(ρ 0 → π + π − γ) = 1.17 · 10 −2 which slightly exceeds the experimental value B exp (ρ 0 → π + π − γ) = (0.99 ± 0.16) · 10 −2 [11].…”
