birth weight
Monday 10 January 2005
Types
low birth weight
high birth weight
Type 2 diabetes
The role of genes in normal birth-weight variation is poorly understood, and it has been suggested that the genetic component of fetal growth is small. Type 2 diabetes genes may influence birth weight through maternal genotype, by increasing maternal glycemia in pregnancy, or through fetal genotype, by altering fetal insulin secretion. (17503332)
