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]

Disclaimer: This variant has not undergone full assessment. The following are preliminary notes: This variant is classified in HGMD as DM, related to HNF1B-related disease (reported in one patient, phenotype not specified). This variant is classified in ClinVar with 1 star as VUS by Emory. It is present in ExAC with a Max MAF of 0.12%. -

Renal cysts and diabetes syndrome

Benign, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Jan 12, 2018	This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -

PreventionGenetics, part of Exact Sciences

May 24, 2024

The HNF1B c.244G>A variant is predicted to result in the amino acid substitution p.Asp82Asn. This variant has been reported in patients with features of HNF1B-related disorders; however, pathogenicity has not been established (Faguer et al. 2014. PubMed ID: 24897035; Brahm et al. 2016. PubMed ID: 27634015; Yu et al. 2019. PubMed ID: 31264968, supplementary table 6; Okorn et al. 2019. PubMed ID: 30666461; Kanda et al. 2016. PubMed ID: 26899772; Zuber et al. 2009. PubMed ID: 19639018). This variant is reported in 0.11% of alleles in individuals of Ashkenazi Jewish descent in gnomAD, which is likely too common to be a primary cause of autosomal dominant disorders. Although we suspect this variant is benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

Ambry Genetics

Dec 20, 2018

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
