Genes affected
PDX1 (HGNC:6107): (pancreatic and duodenal homeobox 1) The protein encoded by this gene is a transcriptional activator of several genes, including insulin, somatostatin, glucokinase, islet amyloid polypeptide, and glucose transporter type 2. The encoded nuclear protein is involved in the early development of the pancreas and plays a major role in glucose-dependent regulation of insulin gene expression. Defects in this gene are a cause of pancreatic agenesis, which can lead to early-onset insulin-dependent diabetes mellitus (IDDM), as well as maturity onset diabetes of the young type 4 (MODY4).

PDX1-related disorder Uncertain:1
Uncertain significance, no assertion criteria providedclinical testingPreventionGenetics, part of Exact SciencesJul 16, 2024The PDX1 c.176A>T variant is predicted to result in the amino acid substitution p.Gln59Leu. This variant was reported in an individual with Diabetes mellitus, type 2 (Hani et al 1999. PubMed ID: 10545531; Ozcan S et al 2002. PubMed ID: 12099699; Bonnefond A et al 2020. PubMed ID: 33046911). This variant is reported in 0.0046% of alleles in individuals of South Asian descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
