Filaggrin mutations in a Western siberian population and their association with atopic dermatitis in children.

We determined the frequencies of null mutations of the FLG gene--2282del4, R501X, R2447X, 3702delG, S3247X, and the 12-repeat allele (rs12730241)--among 460 Caucasians of the city of Novosibirsk, Russia. The frequency was 17.7% for rs12730241, 2.

Polymorphism of arylamine-N-acetyltransferase 2 gene is associated with the risk of atopic dermatitis.

A case--control study was conducted to evaluate the relationship between C481T and G590A polymorphisms of arylamine-N-acetyltransferase 2 and predisposition to atopic dermatitis in children. Double heterozygote 481C/T and 590G/A in girls is a factor of resistance to atopic dermatitis, especially in the absence of smoking-related effects.

Glutathione-S-transferase polymorphism and clinical features of acute drug poisoning in children.

We studied the association of GSTM1 and GSTT1 and GSTP1 Ile105-Val105 polymorphism with the duration of intoxication, polyorgan failure, and severity of drug poisoning in children. The combination of GSTM1 and GSTT1 zero genotypes is a favorable sign for the duration of intoxication and severity of the disease.

Activity of cytochrome P450 in children.

The 6beta-hydroxycortisol/cortisol ratio was measured in 52 children aging 1.1-14.0 years.

Interaction of GSTM1, GSTT1, and GSTP1 genotypes in determination of predisposition to atopic dermatitis.

The frequency of individual genotypes GSTM1, GSTT1, and GSTP1 and haplotypes was determined in patients with atopic dermatitis and healthy children. The actual frequency of some haplotypes was far below the theoretical value. Some haplotypes were associated with predisposition and resistance to atopic dermatitis.
