Genes affected

C12orf43 (HGNC:25719): (chromosome 12 open reading frame 43) Predicted to be involved in Spemann organizer formation and negative regulation of Wnt signaling pathway. Predicted to be located in nuclear envelope. [provided by Alliance of Genome Resources, Apr 2022]

C12orf43 links:

HNF1A (HGNC:11621): (HNF1 homeobox A) The protein encoded by this gene is a transcription factor required for the expression of several liver-specific genes. The encoded protein functions as a homodimer and binds to the inverted palindrome 5'-GTTAATNATTAAC-3'. Defects in this gene are a cause of maturity onset diabetes of the young type 3 (MODY3) and also can result in the appearance of hepatic adenomas. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Apr 2015]
