Red cell enzyme and serum protein polymorphisms (ACP1, PGM1, GLO1, ESD, HP, PI) in Turkish population

Abstract

BACKGROUND:The allele frequencies in human populations are used in different areas such as population genetics, forensic genetics and anthropological studies. Various different populations have been investigated their allele frequency distributions of polymorphic traits. AIMS AND OBJECTIVES:The allele frequency distributions of four red cell enzyme (ACP1, PGM1, GLO1, ESD) and two serum protein systems (HP, PI subtypes) were analyzed in Turkish population from Adana area, Turkey, in order to enlarge our knowledge on the genetic composition of Turkish population. MATERIAL AND METHODS: Venous blood samples taken from 200 unrelated Turkish individuals were transported to the Forensic Serology Laboratory of Albert Szent-Györgyi Medical University (Szeged/Hungary) for phenotyping. The phenotypes of ACP1, PGM1, GLO1, ESD, and HP systems were determined by means of starch gel electrophoresis, while PI subtypes were obtained by polyacrylamide gel isoelectric focusing method. The allele frequencies were calculated by gene counting. RESULTS:The calculated frequencies of the alleles are as follows: ACP1*A = 0.250 ± 0.021, ACP1 *B = 0.693 ± 0.023, ACP1 *C = 0.057 ± 0.011; PGM1 *1 = 0.710 ± 0.022, PGM1*2 = 0.288 ± 0.022, PGM1*6 = 0.002 ± 0.002; GLO1*1 = 0.373 ± 0.024, GLO1*2 = 0.627 ± 0.024; ESD*1 = 0.805 ± 0.019, ESD*2 = 0.195 ± 0.019; HP*1 = 0.265 ± 0.022, HP*2 = 0.735 ± 0.022; PI*M1 = 0.887 ± 0.015, PI*M2 = 0.010 ± 0.004, PI*M3 = 0.095 ± 0.014, PI*S = 0.008 ± 0.004. CONCLUSIONS:The comparison of the data with those of Asian and European populations showed that the allele frequencies of ACP1, ESD and HP are similar or close to those of Asian populations, whereas those of PGM1 and PI come close to European populations. The allele frequency of GLO1 system is inbetween those of Asians and Europeans.

Polymorphic enzymes and proteins in forensic science

“…This technique allowed scientists to identify different forms of enzymes based on their mobility on a gel. [10][11][12][13][14][15][16] One of the most famous examples of enzyme polymorphism is the ABO blood group system. The ABO system is based on the presence of different forms of a glycosyltransferase enzyme that adds sugar molecules to the surface of red blood cells.…”
