Genes affected

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]

Variant summary: HNF1A c.-119G>A is located in the untranslated mRNA region upstream of the initiation codon. The variant allele was found at a frequency of 1.5e-05 in 195996 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.-119G>A has been observed in one individual affected with Maturity Onset Diabetes Of The Young 3 (Godart_2000). These report(s) do not provide unequivocal conclusions about association of the variant with Maturity Onset Diabetes Of The Young 3. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication have been ascertained in the context of this evaluation (PMID: 10649494). ClinVar contains an entry for this variant (Variation ID: 3350786). Based on the evidence outlined above, the variant was classified as uncertain significance. -

Collection Method:clinical testing

The HNF1A c.-119G>A variant is located in the 5' untranslated region. This variant has been reported in a family with maturity onset diabetes of the young (MODY), but the clinical significance is inconclusive (Godart et al. 2000. PubMed ID: 10649494). In the same study, a small deletion variant at the same nucleotide position designated c.-119delG has been reported to segregate with MODY in one family. The c.-119G>A variant is reported in 0.030% of alleles in individuals of African descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
