Allele frequencies and forensically relevant population statistics of 22 short tandem repeat (STR) loci were determined from 303 unrelated Estonian individuals. The samples were amplified with three kits: the AmpFlSTR(®) Identifiler, the PowerPlex(®) ESI 16 and the PowerPlex(®) 16. No significant deviation from Hardy-Weinberg equilibrium was detected, except for locus D22S1045.

The etiology and genetic risk factors of primary open-angle glaucoma are mostly unknown. The aim of this study was to find out whether the polymorphism at GSTM1, GSTM3, GSTT1 and GSTP1 loci is associated with increased susceptibility to glaucoma, because these polymorphic enzymes are susceptibility candidates for several diseases, including such eye disease as cataract.

Purpose: To investigate the possible association between glutathione S-transferase GSTM1, GSTM3, GSTT1, and GSTP1 polymorphism and the occurrence of age-related cataracts in Estonian patients.
Methods: Patients with cortical (155), nuclear (77), posterior subcapsular (120), mixed type (151) of senile cataract and control individuals (202) were phenotyped for GSTM1 and GSTT1 by enzyme-linked immunosorbent assay and genotyped for GSTM3 and GSTP1 by polymerase chain reaction.
Results: The frequency of the GSTM1-positive phenotype was significantly higher in the cortical cataract group (60.
The distribution of glutathione S-transferase T1 (GSTT1) phenotypes was studied in a total sample of 673 Estonians whose four grandparents were born in Estonia, by an ELISA test able to differentiate between GSTT1 positive and GSTT1 negative phenotypes. 18% of the total sample did not present GSTT1-1 protein in whole blood. GSTT1-1 concentration was assayed in 519 out of the 552 GSTT1 positive subjects (i.
