Mutation in HNF4A associated with an increase in birthweight and Macrosomia (birthweight more than 4000g). A mutation in one gene HNF4A, associated with diabetes in the young, has been shown to be associated with an average increase in birthweight. Macrosomia is associated with complications for both mothers and babies; one cause of macrosomia is diabetes in the mother. The particular type of diabetes investigated in this study is known as maturity-onset diabetes of the young (MODY) genes
 "According to Forbes some of the drug company giants are finally realizing that their genetic research is worth more if they give it away. 'Novartis, the Basel, Switzerland, drug giant, has helped uncover which of the 20,000 genes identified by the Human Genome Project are likely to be associated with diabetes. But rather than hoard this information, as drug firms have traditionally done, it is making it available for free on the World Wide Web. "It will take the entire world to interpret these data," says Novartis research head Mark Fishman. "We figure we will benefit more by having a lot of companies look at these data than by holding it secret."'"
