Key result
Variants in the FADS1 FADS2 gene cluster strongly influenced blood polyunsaturated fatty acid levels in children up to 2 years of age, but neither the genetic variants nor the fatty acid levels were significantly associated with eczema in the pooled analysis.
Why the study?
Do genetic variants in the FADS1-FADS2 gene cluster influence blood PUFA levels and eczema risk in children up to 2 years of age?
Cohort (n=879)
Yes
Do genetic variants in the FADS1-FADS2 gene cluster influence blood PUFA levels and eczema risk in children up to 2 years of age?
Odds Ratio: 1.34 (95% CI 0.79–2.28)
p-value: p=0.13
Genetic variants in the FADS1-FADS2 gene cluster strongly control PUFA composition in young children's blood, but there is no consistent link between these variants or blood PUFA levels and the development of eczema.
No eczema link despite strong PUFA effects; hypothesis-generating and should not yet inform dietary or genetic interventions in early childhood.

Rzehak et al. (2010) conducted a cohort in Eczema (n=879). Variants of the FADS1 FADS2 gene cluster (e.g., rs174545) vs. Non-carriers (homozygous major alleles) was evaluated on Parental reported eczema in the first 2 years of life (OR 1.34, 95% CI 0.79-2.28, p=0.13). Variants in the FADS1 FADS2 gene cluster strongly influenced blood polyunsaturated fatty acid levels in children up to 2 years of age, but neither the genetic variants nor the fatty acid levels were significantly associated with eczema in the pooled analysis.
