FSHD region gene 2 family member E, pseudogene (FRG2EP)

FRG2EP (FSHD region gene 2 family member E, pseudogene) is a pseudogene located in the FSHD region of the genome. While some FRG2 family members are candidate genes implicated in FSHD—where changes in transcription may play a role in this muscular dystrophy—FRG2EP itself is nonfunctional and does not code a protein product[3][7]. It is currently not attributed any direct biological function, nor is it recognized as a therapeutic or diagnostic target. There is no evidence that FRG2EP interacts with known drugs or is directly implicated in disease pathogenesis. Some sources ambiguously describe possible regulatory roles for FRG2 family genes in immune response or myogenesis[1][5], but these refer to protein-coding homologues (such as FRG2 or FRG2B), not the FRG2EP pseudogene. There is no reliable evidence that FRG2EP exerts any functional regulatory effect in human physiology[3][7]. Any conflicting or speculative statements about function (such as described as an "inflammasome regulator"[5]) are not supported in authoritative gene databases and should be treated with caution because these attributions are likely confused with other FRG2 family paralogs and not FRG2EP specifically.
