HNF1 homeobox A (hepatocyte nuclear factor 1 homeobox A), also known as HNF1A, is a human gene.^[1][2]

The protein encoded by this gene is a transcription factor that is highly expressed in the liver and is involved in the regulation of the expression of several liver-specific genes.^[3]

Clinical significance

HNF1A mutations can cause maturity onset diabetes of the young type 3, one of the forms of "monogenic diabetes",^[2] as well as hepatocellular adenoma. HNF-1 protein is present in clear cell carcinoma of ovary ^[4][5]

Interactions

HNF1A has been shown to interact with:

• CREB-binding protein^[6] and
• EP300,^[7]
• PCAF,^[6]
• PCBD1,^[8][9]
• RAC3,^[6] and
• Src.^[6]
