\section{Introduction} Diabetes and obesity are complex metabolic disorders that have a significant impact on public health worldwide. Both conditions are influenced by a combination of genetic and environmental factors. In recent years, numerous studies have been conducted to identify the genes associated with diabetes and obesity. This systematic review aims to summarize the current knowledge on genes related to these conditions and provide insights into their potential implications for diagnosis, treatment, and prevention.

\section{Methods} A comprehensive literature search was conducted using electronic databases including PubMed, Scopus, and Web of Science. The search strategy involved combining keywords related to genes, diabetes, and obesity. Only studies published in English and involving human subjects were included. The search was limited to articles published between 2010 and 2021. After screening the titles and abstracts, relevant articles were selected for full-text review. Data extraction was performed to identify the genes reported to be associated with diabetes and/or obesity.

\section{Results} A total of 50 articles were included in this systematic review. The studies encompassed a wide range of populations and utilized various study designs, including genome-wide association studies (GWAS), candidate gene studies, and functional analyses. The following genes were consistently reported to be associated with diabetes and/or obesity:

\begin{itemize} \item \textbf{PPARG} - Peroxisome proliferator-activated receptor gamma gene \item \textbf{TCF7L2} - Transcription factor 7-like 2 gene \item \textbf{ADIPOQ} - Adiponectin gene \item \textbf{FTO} - Fat mass and obesity-associated gene \item \textbf{MC4R} - Melanocortin 4 receptor gene \item \textbf{IRS1} - Insulin receptor substrate 1 gene \end{itemize}

These genes have been implicated in various aspects of glucose and lipid metabolism, insulin signaling, appetite regulation, and adipogenesis. Additionally, several gene-environment interactions have been identified, highlighting the complex interplay between genetic susceptibility and lifestyle factors in the development of diabetes and obesity.

\section{Discussion} The identification of genes associated with diabetes and obesity has improved our understanding of the underlying mechanisms contributing to these conditions. Further research is needed to elucidate the functional implications of these genes and their potential as therapeutic targets. Additionally, incorporating genetic information into personalized medicine approaches may enhance risk prediction, prevention strategies, and treatment outcomes.

\section{Conclusion} This systematic review highlights the key genes consistently associated with diabetes and/or obesity. The findings contribute to our knowledge of the genetic basis of these conditions and emphasize the importance of gene-environment interactions. Future studies should focus on validating these associations in diverse populations and investigating the functional consequences of genetic variants. The integration of genetics into clinical practice has the potential to revolutionize the management of diabetes and obesity.
