▶COX2 and NOS3 gene polymorphisms in women with gestational diabetesReviewMaciej Tarnowski et al.(2017)· The Journal of Gene Medicine
This comprehensive review synthesizes literature on gestational diabetes mellitus (GDM), demonstrating its complex multifactorial etiology involving genetic factors (SNPs in GCKR, KCNQ1, MTNR1B, TCF7L2), epigenetic modifications (DNA methylation and microRNA expression), and alterations in microbial composition across multiple body sites. While certain SNP variants are associated with GDM phenotypes globally, genetic predisposition alone does not explain disease development; lifestyle factors can modify epigenetic signatures and microbiota composition to modulate risk. Evidence indicates genes, epigenetic alterations, and microbiota can transfer from mother to offspring with long-term health consequences.
▶Common variants in MODY genes increase the risk of gestational diabetes mellitusAssociationN=1,880Shaat N. et al.(2006)· Diabetologia
This case-control study of 1,880 Scandinavian women (648 with gestational diabetes mellitus [GDM] and 1,232 controls) examined common variants in MODY genes. The GCK -30G→A polymorphism (rs1799884) showed increased GDM risk in an additive model (OR 1.28, 95% CI 1.06–1.53, p=0.008) and recessive model (OR 2.12, p=0.009). The HNF1A I27L polymorphism (rs1169288) showed modest increased risk with a dominant model (OR 1.31, p=0.007). Three HNF4A variants (rs2144908, rs2425637, rs1885088) were not associated with GDM risk.
▶Genetic epidemiology of MODY in the Czech republic: new mutations in the MODY genes HNF-4α, GCK and HNF-1αAssociationN=263Pruhova S. et al.(2003)· Diabetologia
Genetic screening of 61 Czech MODY families identified 20 mutations in HNF-4α, GCK, and HNF-1α genes in 48% of families (5% MODY1, 31% MODY2, 11.5% MODY3 prevalence). Seventy percent of identified mutations were novel, including Arg125Trp and Val121Ile in HNF-4α, Glu40Lys and Gly44Asp in GCK, and Arg200Gly in HNF-1α, suggesting that most MODY mutations in this Central European population are local variants.
About HNF1A
The protein encoded by this gene is a transcription factor required for the expression of several liver-specific genes. The encoded protein functions as a homodimer and binds to the inverted palindrome 5'-GTTAATNATTAAC-3'. Defects in this gene are a cause of maturity onset diabetes of the young type 3 (MODY3) and also can result in the appearance of hepatic adenomas. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Apr 2015]
