\section{Introduction} Diabetes and obesity are complex metabolic disorders with a significant global health impact. Both conditions are influenced by a combination of genetic and environmental factors. Extensive research has been conducted to identify genes associated with these diseases. This article provides an overview of some of the genes linked to diabetes and/or obesity.

\section{Genes Related to Diabetes} \subsection{TCF7L2} The transcription factor 7-like 2 (TCF7L2) gene has been extensively studied in relation to type 2 diabetes. Variants in this gene have consistently shown significant associations with an increased risk of developing type 2 diabetes \cite{grant2006variant}. TCF7L2 is involved in the regulation of glucose metabolism and insulin secretion.

\subsection{PPARG} The peroxisome proliferator-activated receptor gamma (PPARG) gene is another well-known gene associated with diabetes. Variants in this gene have been linked to an increased risk of insulin resistance and type 2 diabetes \cite{deeb1998a}. PPARG plays a crucial role in adipocyte differentiation and lipid metabolism.

\subsection{KCNJ11} The potassium inwardly-rectifying channel, subfamily J, member 11 (KCNJ11) gene has been implicated in both type 2 diabetes and neonatal diabetes. Variants in this gene affect the function of the ATP-sensitive potassium channels in pancreatic beta cells, leading to impaired insulin secretion \cite{gloyn2003activating}.

\section{Genes Related to Obesity} \subsection{FTO} The fat mass and obesity-associated (FTO) gene is one of the most extensively studied genes associated with obesity. Variants in FTO have consistently shown strong associations with increased body mass index (BMI) and obesity risk \cite{frayling2007common}. FTO is involved in the regulation of energy homeostasis and appetite control.

\subsection{MC4R} The melanocortin 4 receptor (MC4R) gene is another important gene associated with obesity. Loss-of-function mutations in MC4R lead to a rare form of monogenic obesity \cite{farooqi2003clinical}. MC4R plays a crucial role in the central regulation of energy balance and satiety.

\subsection{LEP} The leptin (LEP) gene encodes the hormone leptin, which plays a key role in appetite regulation and energy balance. Mutations in LEP or its receptor (LEPR) can cause severe obesity due to disrupted leptin signaling \cite{farooqi2001clinical}. Leptin deficiency or resistance leads to uncontrolled food intake and reduced energy expenditure.

\section{Conclusion} Understanding the genetic factors underlying diabetes and obesity is crucial for developing effective prevention and treatment strategies. The genes mentioned in this article represent just a fraction of the many genetic variants associated with these conditions. Further research is needed to unravel the complex interplay between genetics, environment, and lifestyle factors in the development of diabetes and obesity.

This example provides a structure for a LaTeX article on genes related to diabetes and obesity. It includes an introduction, sections on diabetes and obesity genes, and a conclusion. Each gene has a subsection with a brief description of its association with the disorders. References are cited using the \texttt{plain} bibliography style, stored in a separate \texttt{.bib} file named \texttt{references.bib}.
