摘要

Obesity is one of the largest global health problems associated with increased morbidity and mortality mediated by its association with several other metabolic disorders. The interaction between the genes and environment plays an important role in the manifestation of obesity. Despite a high heritability (40a??70%) of obesity, the search for genetic variants associated with obesity susceptibility has been a challenging task. To date, limited studies have been conducted in India, restricted to the validation of few genetic variants identified by genomewide association studies. In this critical review, we sought to examine the current knowledge ofgenetic basis of obesity and its measures in the Indian population. A comprehensive literature search was performed using a??PubMeda??, a??Medlinea?? and a??IndMeda?? databases to search for citations published until 31st May 2017, using the key terms as a??Geneticsa?? AND a??obesitya?? AND a??Indiaa??. We identified 48 potential studies which fulfilled the eligibility criteria. The findings indicated thatFTO , MC4R, TNF-?±, PPAR-?3 , UCP1, UCP2, LPL, LEPR, AMD1, IL6, APOE, ADIPOQ, DOK5, INSIG2, PBEF1, IL6R, Myostatin, CXCR4, HHEX, IRX3, POMC, NGN3, FOXA2, MTR, TCN and CHDH are some of the important genes studied among the Indian population. Importantly, the role of sexual dimorphism in the genetic regulation of obesity and body fat distribution was also reported in a few studies. Further, seven biological pathways have been identified that contribute to obesity pathogenesis in India. In conclusion, further exploration of pathway-based research on genetics of obesity can be useful for better understanding thepathophysiology of obesity in India.

IndMeda ??数据库检索使用2017年5月31日之前发布的引文,并使用关键词“ Geneticsa”还有一个?肥胖症?和一个??印度??。我们确定了48项符合资格标准的潜在研究。结果表明FTO,MC4R,TNF-α±,PPAR-β3,UCP1,UCP2,LPL,LEPR,AMD1,IL6,APOE,ADIPOQ,DOK5,INSIG2,PBEF1,IL6R,肌生长抑制素,CXCR4,HHEX,IRX3,POMC NGN3,FOXA2,MTR,TCN和CHDH是印度人群中研究的重要基因。重要的是,一些研究还报道了性二态性在肥胖和体脂分布的遗传调控中的作用。此外,已经确定了有助于印度肥胖症发病机理的七种生物学途径。总之,进一步探索基于途径的肥胖症遗传学研究可能有助于更好地了解印度肥胖症的病理生理学。
