The changes in PBMC IFNG mRNA expression correlated with the reported intake of CSO (portions per day) (n = 17; ρ = −0.44, P = 0.08), but did not correlate with the changes in ALA proportions in either CE or PL fractions (n = 72; ρ = −0.17, P = 0.15 and ρ = −0.16, P = 0.19, respectively; CSO group, n = 17: ρ = −0.06, P = 0.82 and ρ = −0.23, P = 0.38, respectively). Here, IFNG is linked to craniosynostosis.
