Genetic variation of FTO: rs1421085 T&gt;C, rs8057044 G&gt;A, rs9939609 T&gt;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.

Common variants near BDNF and SH2B1 show nominal evidence of association with snacking behavior in European populations
AssociationN=14,000Sébastien Robiou-du-Pont et al.(2013)· Journal of Molecular Medicine

Genome-wide association study examining common variants near BDNF (rs6265, rs925946) and SH2B1 (rs7498665) in relation to snacking behavior across three European cohorts (French obese children, Swiss obese, D.E.S.I.R.). The study reports nominal evidence of association, with rs925946 in BDNF showing OR=1.21 (p=5.03×10⁻³) in the D.E.S.I.R. cohort and rs7498665 in SH2B1 showing OR=1.17 (p=9.57×10⁻³) in the Swiss cohort.

ReviewCarmen Martínez et al.(2010)· Hepatology

A comprehensive review of nutrigenetics and nutrigenomics examining how genetic variants influence individual responses to nutrients and dietary interventions. The paper discusses associations between numerous SNPs (rs9939609 in FTO, rs2287019 in GIPR, rs7903146 in TCF7L2, rs5219 in KCNJ11, and many others) and metabolic traits including obesity, type 2 diabetes, and other chronic diseases, along with epigenetic mechanisms by which phytochemicals (curcumin, resveratrol, lycopene) modulate gene expression. The review synthesizes current evidence for precision nutrition approaches tailored to individual genetic profiles.

About PCSK1

This gene encodes a member of the subtilisin-like proprotein convertase family, which includes proteases that process protein and peptide precursors trafficking through regulated or constitutive branches of the secretory pathway. The encoded protein undergoes an initial autocatalytic processing event in the ER to generate a heterodimer which exits the ER and sorts to subcellular compartments where a second autocatalytic even takes place and the catalytic activity is acquired. The protease is packaged into and activated in dense core secretory granules and expressed in the neuroendocrine system and brain. This gene encodes one of the seven basic amino acid-specific members which cleave their substrates at single or paired basic residues. It functions in the proteolytic activation of polypeptide hormones and neuropeptides precursors. Mutations in this gene have been associated with susceptibility to obesity and proprotein convertase 1/3 deficiency. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene [provided by RefSeq, Jan 2014]
