Genes affected

FEV (HGNC:18562): (FEV transcription factor, ETS family member) This gene belongs to the ETS transcription factor family. ETS family members have a highly conserved 85-amino acid ETS domain that binds purine-rich DNA sequences. The alanine-rich C-terminus of this gene indicates that it may act as a transcription repressor. This gene is exclusively expressed in neurons of the central serotonin (5-HT) system, a system implicated in the pathogeny of such psychiatric diseases as depression, anxiety, and eating disorders. In some types of Ewing tumors, this gene is fused to the Ewing sarcoma (EWS) gene following chromosome translocations. [provided by RefSeq, Jul 2008]

The c.616G>C (p.A206P) alteration is located in exon 3 (coding exon 3) of the FEV gene. This alteration results from a G to C substitution at nucleotide position 616, causing the alanine (A) at amino acid position 206 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
