, has been investigated with respect to increased intelligence in breastfed children but not yielded any clear result.
- Although there was no difference in IQ linked to the SNP alone, breastfed children carrying one or two copies of rs174575(C) had a significant (6 point) increase in IQ compared to carriers of the same allele who were not breastfed. For children who were homozygous non-carriers, i.e. rs174575(G;G) individuals, there was no effect of breastfeeding on IQ. [PMID 17984066]
- did not replicate those findings. In contrast to their study, (G;G) children exhibited the greatest difference between feeding methods such that breastfed children performed similarly irrespective of child genotype whereas formula fed (G;G) children performed worse than other children on formula milk [PMID 20644632]
