Abstract:
Neutrality investigations of markers with forensic use are important to see if a phenotypic trait is being expressed in relation to the alleles of the marker. MiniSTR marker D22S1045 (locus 22q12.3) is localized near the breakpoint region of the EWS gene (22q12.2), which leads to the development of Ewing's Sarcoma. Analyzing allele frequencies and linkage disequilibrium in Ewing's sarcoma patients and non-affected populations, we found that the marker mD22S1045 was neutral when related to Ewing's Sarcoma.
