Genes could increase risk of childhood obesity

Obesity is a common topic in science now-a-days because of how high the obesity rate is.  Science Daily released that geneticists have identified two genes that can increase the risk to childhood obesity.In the past there were other genes as well that have been identified for this, but those are only for extreme cases. These genes are known to be linked to "common" childhood obesity.  There was a massive study which included 13,830 children. This was the largest study ever on common childhood obesity. The data allowed them to locate where the role of obesity may further come from. The OLFM4 gene on chromosome 13, and HOXB5 gene on chromosome 17 were never previously studied for this problem. In the future this may allow for treatments and preventatives to be designed based on children's genome.

Genes Identified in Common Childhood Obesity

An article in Science Daily, talks about researchers recently discovering at least two new gene variants that are common among obese children.  Struan F.A. Grant, Ph.D.,lead investigator, and associate director of the Center for Applied Genomics at The Children's Hospital of Philadelphia is in charge of the largest ever genome wide study of common childhood obesity.  Their research has been able to identify and characterize a genetic predisposition to obesity among children.  The study was conducted as an international effort to better understand this major health issue plaguing modern day society.   Of course many people blame the  obvious environmental factors for causing obesity studies of twins and other family based research have provided a possible genetic influence.  Past studies have found connections to adults and children that have extreme obesity but none have shed light in regular childhood obesity. The current analysis included 14 previous studies encompassing 5,530 cases of childhood obesity and 8,300 control subjects, all of European ancestry. The study team identified two novel loci, one near the OLFM4 gene on chromosome 13, the other within the HOXB5

gene on chromosome 17. They also found a degree of evidence for two other gene variants. None of the genes were previously implicated in obesity.  More research is needed but these findings may be useful in creating a preventative inerventions for children based on their genomes.

Childhood obesity is a growing world wide health issue and if genetic research can help children prevent this condition than we need to fund more research to benefit society and its struggle with this condition.
