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).

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -2 ACMG points.

PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 7 curated pathogenic missense variants (we use a threshold of 10). The gene has 1 curated benign missense variants. Gene score misZ: -0.26592 (below the threshold of 3.09). Trascript score misZ: -1.1553 (below the threshold of 3.09). GenCC associations: The gene is linked to pancreatic agenesis 1, monogenic diabetes, pancreatic agenesis, maturity-onset diabetes of the young, permanent neonatal diabetes mellitus, maturity-onset diabetes of the young type 4.
BP4
Computational evidence support a benign effect (MetaRNN=0.10159895).
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000092 (14/152238) while in subpopulation AFR AF = 0.000289 (12/41470). AF 95% confidence interval is 0.000167. There are 0 homozygotes in GnomAd4. There are 6 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
