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]

Submissions by phenotype
Renal cysts and diabetes syndrome Benign:1
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. - |
Maturity onset diabetes mellitus in young Benign:1
Likely benign, criteria provided, single submitter | research | Clinical Genomics, Uppaluri K&H Personalized Medicine Clinic | - | HNF1B gene mutations are associated with early onset diabetes and pancreatic atrophy. It is also associated with multiple renal manifestations including renal cysts, Tubulointerstitial disease, glomerulocystic disease, renal hypoplasia, hypomagnesemia. However no sufficient evidence is found to ascertain the role of this particular variant rs144234352, yet. - |
