Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the HNF1A gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

Function
FUNCTION: Transcriptional activator that regulates the tissue specific expression of multiple genes, especially in pancreatic islet cells and in liver. Required for the expression of several liver specific genes. Binds to the inverted palindrome 5'- GTTAATNATTAAC-3'. {ECO:0000269|PubMed:10966642, ECO:0000269|PubMed:12453420}.;
Disease
DISEASE: Hepatic adenomas familial (HEPAF) [MIM:142330]: Rare benign liver tumors of presumable epithelial origin that develop in an otherwise normal liver. Hepatic adenomas may be single or multiple. They consist of sheets of well-differentiated hepatocytes that contain fat and glycogen and can produce bile. Bile ducts or portal areas are absent. Kupffer cells, if present, are reduced in number and are non-functional. Conditions associated with adenomas are insulin-dependent diabetes mellitus and glycogen storage diseases (types 1 and 3). Note=The disease is caused by mutations affecting the gene represented in this entry. Bi-allelic inactivation of HNF1A, whether sporadic or associated with MODY3, may be an early step in the development of some hepatocellular carcinomas.; DISEASE: Maturity-onset diabetes of the young 3 (MODY3) [MIM:600496]: A form of diabetes that is characterized by an autosomal dominant mode of inheritance, onset in childhood or early adulthood (usually before 25 years of age), a primary defect in insulin secretion and frequent insulin-independence at the beginning of the disease. {ECO:0000269|PubMed:10078571, ECO:0000269|PubMed:10102714, ECO:0000269|PubMed:10482964, ECO:0000269|PubMed:10588527, ECO:0000269|PubMed:10966642, ECO:0000269|PubMed:12453420, ECO:0000269|PubMed:17573900, ECO:0000269|PubMed:8945470, ECO:0000269|PubMed:9032114, ECO:0000269|PubMed:9075818, ECO:0000269|PubMed:9075819, ECO:0000269|PubMed:9097962, ECO:0000269|PubMed:9166684, ECO:0000269|PubMed:9287053, ECO:0000269|PubMed:9392505, ECO:0000269|PubMed:9626139, ECO:0000269|PubMed:9754819}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Diabetes mellitus, insulin-dependent, 20 (IDDM20) [MIM:612520]: A multifactorial disorder of glucose homeostasis that is characterized by susceptibility to ketoacidosis in the absence of insulin therapy. Clinical features are polydipsia, polyphagia and polyuria which result from hyperglycemia-induced osmotic diuresis and secondary thirst. These derangements result in long-term complications that affect the eyes, kidneys, nerves, and blood vessels. {ECO:0000269|PubMed:10333057, ECO:0000269|PubMed:9313763, ECO:0000269|PubMed:9867222}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.;
