Genes affected

FOXO3 (HGNC:3821): (forkhead box O3) This gene belongs to the forkhead family of transcription factors which are characterized by a distinct forkhead domain. This gene likely functions as a trigger for apoptosis through expression of genes necessary for cell death. Translocation of this gene with the MLL gene is associated with secondary acute leukemia. Alternatively spliced transcript variants encoding the same protein have been observed. [provided by RefSeq, Jul 2008]

The c.431C>G (p.S144C) alteration is located in exon 1 (coding exon 1) of the FOXO3 gene. This alteration results from a C to G substitution at nucleotide position 431, causing the serine (S) at amino acid position 144 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
