SLC30A8 and MODY: ▪GDM-related genetic mutations:-Genetic mutations in some specific genes are related to the development of GDM, such as the following genes: transcription factor 7-like 2 (TCF7L2), CDKAL1, Transcription factor 2 (TCF2), Fat mass- and obesity-associated gene (FTO), CDKN2A/2B, HHEX, Insulin-like growth factor 2 MRNA binding protein 2, Solute carrier family 30 member 8 gene (IGF2BP2), and SCL30A8.-Some women, although uncommon among pregnant women with GDM, have genetic variants that are monogenic forms of diabetes, including genes for subtypes maturity onset diabetes of the young (MODY).
