Effect of human leukocyte antigen B*1502 genotype and age on serum homocysteine levels in children with seizures or epilepsy / 临床儿科杂志

ABSTRACT

Objective To explore the effect of human leukocyte antigen B* genotype and age on serum homocysteine (Hcy) levels in children with seizures or epilepsy. Methods Fifteen children with seizures or epilepsy in whom HLA-B*1502 genotype was detected during October 2015 to June 2016 were included. The plasma Hcy concentration in children with different genotypes was compared. The association of Hcy concentration and age was performed by linear-regression analysis. Results The mean concentration of Hcy was 8.38±4.23 μmol/L in children not carrying HLA-B*1502 gene, which was obviously higher than that in children carrying HLA-B*1502 gene 13.03±0.97 μmol/L (P<0.05). The Hcy concentration increased with the age (r2 =0.29, P<0.05). Conclusions Elder children with seizures or epilepsy carrying HLA-B*1502 gene tend to have higher Hcy concentration and increased potential risk of disease. HLA-B*1502 gene type and age can predict the changes of Hcy concentration in children with convulsions.
