Genes affected

FOXA2 (HGNC:5022): (forkhead box A2) This gene encodes a member of the forkhead class of DNA-binding proteins. These hepatocyte nuclear factors are transcriptional activators for liver-specific genes such as albumin and transthyretin, and they also interact with chromatin. Similar family members in mice have roles in the regulation of metabolism and in the differentiation of the pancreas and liver. This gene has been linked to sporadic cases of maturity-onset diabetes of the young. Transcript variants encoding different isoforms have been identified for this gene.

The c.1073C>A (p.P358Q) alteration is located in exon 2 (coding exon 2) of the FOXA2 gene. This alteration results from a C to A substitution at nucleotide position 1073, causing the proline (P) at amino acid position 358 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
