Genes affected

FOXO4 (HGNC:7139): (forkhead box O4) This gene encodes a member of the O class of winged helix/forkhead transcription factor family. Proteins encoded by this class are regulated by factors involved in growth and differentiation indicating they play a role in these processes. A translocation involving this gene on chromosome X and the homolog of the Drosophila trithorax gene, encoding a DNA binding protein, located on chromosome 11 is associated with leukemia. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2010]

The c.562G>A (p.G188S) alteration is located in exon 2 (coding exon 2) of the FOXO4 gene. This alteration results from a G to A substitution at nucleotide position 562, causing the glycine (G) at amino acid position 188 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
