Genetic polymorphism of human factor H (HF, beta 1H globulin) in Chinese Han population in northeast China.

The distribution of human factor H of serum phenotypes were studied using ultrathin polyacrylamide gel isoelectric focusing (PAGIEF) and subsequent immunoblotting techniques in 203 Chinese of Han population in Liaoning Province of northeast China. The gene frequencies of HF*A and HF*B were 0.4828 and 0.5172, respectively. All the observed numbers of the phenotypes were in agreement with the expected numbers under the Hardy-Weinberg equilibrium. The gene frequencies among Chinese, Japanese, and Caucasian populations were compared.

Genetic polymorphisms and intrauterine development. Evidence of decreased heterozygosity in light-for-dates human newborn babies.

In 2 independent samples of low-birth-weight infants the proportion of females and homozygotes for a series of polymorphic systems was higher in light-for-dates than in preterm babies. The observation seems to give support to the hypothesis that homozygosity for 'normal' polymorphisms may decrease in general intrauterine growth rate. Since it is known that survival rate is strongly related to birth weight, a correlation between growth retardation and homozygosity may have a major role in the maintenance of such polimorphisms.

Genetic polymorphisms analysis of glutathione S-transferase M1 and T1 in children with acute lymphoblastic leukemia.

The relationship between glutathione S-transferases (GSTs) M1, T1 genotype and childhood acute lymphoblastic leukemia (ALL) was investigated. GSTM1 and GSTT1 genotypes in genomic DNA from 67 children with ALL and 146 healthy controls were analyzed by using the multiplex polymerase chain reaction (PCR). The frequencies of GSTM1, M1-T1 null genotypes in ALL children were significantly higher than in the healthy controls (76.12% versus 52.74%, OR=2.856, P<0.001; 50.74% versus 24.66%, OR=3.148, P<0.001, respectively). However, there was no significant relationship between GSTT1 null genotype and ALL of children (61.19% versus 49.32%, OR=1.621, P>0.05). It was suggested that GSTM1 null genotype might be a risk genotype of childhood ALL, while there as no correlation between GSTT1 null genotype and childhood ALL.
