MUTATION, French law. This term is synonymous with change, and is particularly applied to designate the change which takes place in the property of a thing in its transmission from one person to another; permutation therefore happens when, the owner of the thing sells, exchanges or gives it. It is nearly synonymous with transfer. (q.v.) Merl. Repert. h.t.

However, different clinical cutoffs have been proposed to discriminate between high- and low-risk patients with SM based on KIT D816V mutant allele burden.
Analysis of alleles conferring resistance to antifolate drugs (Pfdhfr and Pfdhps) showed that the prevalence of mutant alleles was generally high in field samples collected in 2003-2005 (Table 1).
Considering all genetic SNPs with a mutant allele as input variables, the following SNP genotypes were found to be significantly positively associated with the risk of miscarriage: TLR9 AA (z = 4.180, p = 2.92e - 05), TLR9 GA (z = 4.184, p = 2.87 e - 05), IL-10 CA (z = 3.573, p = 0.000353), TLR2 GA (z = 3.027, p = 0.00247), and IL-8 CT (z = 2.862, p = 0.004205).
