Genetic variation of FTO: rs1421085 T>C, rs8057044 G>A, rs9939609 T>A, and copy number (CNV) in Mexican Mayan school‐aged children with obesity/overweight and with normal weight

ReviewLizbeth González‐Herrera et al.(2019)· American Journal of Human Biology

A literature review of 70 studies examining single nucleotide polymorphisms (SNPs) associated with obesity in Mexican populations published 2011-2021. The authors identified SNPs with differential behavior in Mexican compared to Caucasian populations, including rs17782313 (MC4R), rs6548238 (TMEM18), rs6265 (BDNF), rs7498665 (SH2B1), and notably rs6232 (PCSK1) associated with early-onset obesity in Mexican youth. The review emphasizes ethnicity-dependent genetic effects on BMI heritability (40-70%) and highlights genes involved in cholesterol metabolism and adipokine signaling pathways.

Association of genetic variants for susceptibility to obesity with type 2 diabetes in Japanese individuals

AssociationN=18,264Takeuchi F. et al.(2011)· Diabetologia

Replication study of 14 obesity-associated SNPs from 13 loci in 18,264 Japanese participants, confirming associations at 11 loci including TMEM18 (rs4854344, p=7.1×10⁻⁷ for BMI), FTO, MC4R, BDNF, and others. Six obesity variants also associated with type 2 diabetes after BMI adjustment (OR 1.05-1.17), with FTO showing strong meta-analyzed association in East Asians (OR 1.13, p=7.8×10⁻¹⁰).

About SH2B1

This gene encodes a member of the SH2-domain containing mediators family. The encoded protein mediates activation of various kinases and may function in cytokine and growth factor receptor signaling and cellular transformation. Alternatively spliced transcript variants have been described. [provided by RefSeq, Mar 2009]
