Genes affected

RBFOX2 (HGNC:9906): (RNA binding fox-1 homolog 2) This gene is one of several human genes similar to the C. elegans gene Fox-1. This gene encodes an RNA binding protein that is thought to be a key regulator of alternative exon splicing in the nervous system and other cell types. The protein binds to a conserved UGCAUG element found downstream of many alternatively spliced exons and promotes inclusion of the alternative exon in mature transcripts. The protein also interacts with the estrogen receptor 1 transcription factor and regulates estrogen receptor 1 transcriptional activity. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

The c.1249G>A (p.V417M) alteration is located in exon 13 (coding exon 13) of the RBFOX2 gene. This alteration results from a G to A substitution at nucleotide position 1249, causing the valine (V) at amino acid position 417 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
