Genes affected

HNF1B (HGNC:11630): (HNF1 homeobox B) This gene encodes a member of the homeodomain-containing superfamily of transcription factors. The protein binds to DNA as either a homodimer, or a heterodimer with the related protein hepatocyte nuclear factor 1-alpha. The gene has been shown to function in nephron development, and regulates development of the embryonic pancreas. Mutations in this gene result in renal cysts and diabetes syndrome and noninsulin-dependent diabetes mellitus, and expression of this gene is altered in some types of cancer. Multiple transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Sep 2009]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -12 ACMG points.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 72 curated pathogenic missense variants (we use a threshold of 10). The gene has 9 curated benign missense variants. Trascript score misZ: 2.0703 (below the threshold of 3.09). GenCC associations: The gene is linked to unilateral multicystic dysplastic kidney, renal dysplasia, unilateral, renal cysts and diabetes syndrome, medullary sponge kidney, renal hypomagnesemia 2, renal dysplasia, bilateral, diabetes mellitus, noninsulin-dependent, transient neonatal diabetes mellitus, permanent neonatal diabetes mellitus.

BP4

Computational evidence support a benign effect (MetaRNN=0.008750111).

BP6

Variant 17-37744812-C-A is Benign according to our data. Variant chr17-37744812-C-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 36852.

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.00125 (191/152290) while in subpopulation SAS AF = 0.0352 (170/4826). AF 95% confidence interval is 0.0309. There are 4 homozygotes in GnomAd4. There are 134 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High AC in GnomAd4 at 191 AD gene.
