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 -19 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: NaN (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=0.0018926263).

BP6

Variant 17-37687325-A-C is Benign according to our data. Variant chr17-37687325-A-C is described in ClinVar as Benign. ClinVar VariationId is 322943.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BA1

GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.092 is higher than 0.05.
