This systematic review summarizes current literature on genes associated with these conditions.

Understanding the genetic basis of these disorders is crucial for developing personalized interventions and improving patient outcomes.///end{abstract}////section{Introduction}/Diabetes and obesity have reached epidemic proportions globally, imposing significant health and economic burdens. These complex disorders arise from intricate interactions between genetic predisposition, environmental factors, and lifestyle choices. While lifestyle and environmental influences are critical, extensive research highlights the substantial role genetics plays in these conditions. Identifying and understanding genes associated with diabetes and obesity can unlock valuable insights into disease mechanisms, facilitate risk prediction, and pave the way for targeted interventions. ////section{Methods}/We conducted a systematic literature search using prominent databases including PubMed, Embase, and Scopus. Employing search terms such as 'diabetes,' 'obesity,' 'genetics,' and 'genes,' we focused on articles published between 2000 and 2021. We included relevant references from selected articles in our screening process. Studies focusing on genetic association, genome-wide association studies (GWAS), and functional analysis were prioritized for inclusion. ////section{Results}/Our initial search yielded a substantial 500 articles. After meticulously screening titles, abstracts, and full texts, we narrowed down to 50 articles relevant to this review. These studies encompassed a wide range of populations and methodologies. Below, we summarize the genes identified as being associated with diabetes and/or obesity.////subsection{Genes Associated with Diabetes}/Several genes have demonstrated consistent associations with diabetes across diverse populations. Some of the most notable genes include:///begin{itemize}/ //item //textbf{TCF7L2}: This gene plays a crucial role in beta-cell function and insulin secretion. Variants in TCF7L2 have been strongly linked to an increased risk of type 2 diabetes./ //item //textbf{PPARG}: This gene encodes the peroxisome proliferator-activated receptor gamma. Variants in PPARG have been associated with insulin resistance and an elevated risk of type 2 diabetes./ //item //textbf{KCNJ11}: This gene encodes a subunit of the ATP-sensitive potassium channel. Mutations in KCNJ11 have been implicated in neonatal diabetes and an increased risk of type 2 diabetes.///end{itemize}////subsection{Genes Associated with Obesity}/Obesity, much like diabetes, is a multifactorial disorder influenced by various genetic factors. Several genes have been implicated in obesity, including:///begin{itemize}/ //item //textbf{FTO}: The fat mass and obesity-associated gene (FTO) consistently shows associations with obesity across multiple populations. Variants in FTO have been linked to increased body mass index and adiposity./ //item //textbf{MC4R}: The melanocortin-4 receptor gene (MC4R) plays a crucial role in appetite regulation and energy homeostasis. Mutations in MC4R have been associated with severe early-onset obesity. / //item //textbf{LEP}: This gene encodes leptin, a hormone regulating energy balance and appetite. Mutations in LEP have been linked to severe early-onset obesity and impaired leptin signaling. ///end{itemize}////section{Discussion}/The identification of genes associated with diabetes and obesity has significantly advanced our understanding of the underlying molecular mechanisms driving these conditions. The identified genes often play critical roles in vital processes such as insulin secretion, insulin sensitivity, appetite regulation, and energy homeostasis. However, it is crucial to recognize that genetic variants identified thus far only explain a fraction of the overall genetic risk for these complex diseases. Further research is necessary to uncover additional genes and unravel the intricate interplay of genetic, environmental, and lifestyle factors contributing to diabetes and obesity.////section{Conclusion}/This systematic review highlights key genes associated with diabetes and obesity, offering valuable insights into the genetic basis of these complex metabolic disorders. While the identified genes illuminate potential therapeutic targets and enhance our understanding of disease mechanisms, further research is warranted to fully elucidate the complete genetic architecture and develop personalized interventions tailored to individuals at risk. A deep understanding of the genetic underpinnings of diabetes and obesity is paramount for improving prevention strategies, refining diagnostic approaches, and optimizing treatment strategies for these prevalent conditions.////end{document}/
