FSHD region gene 2 family member B (FRG2B)

FRG2B (FSHD region gene 2 family member B) encodes a paralog of the FRG2 gene and is predicted primarily to produce noncoding RNAs highly similar to FRG2A, contributing to chromatin structure and nucleolar organization rather than classical protein function[1][2][5]. FRG2B transcript is enriched in the nucleus and is associated with heterochromatin, with a nucleolar sub-compartment localization. FRG2B, together with its paralogs, is thought to contribute to nuclear architecture as a scaffold for heterochromatin interactions with nucleolar periphery and has been investigated in the context of neuromuscular disease, especially as part of a locus altered in facioscapulohumeral muscular dystrophy. There is no definitive evidence supporting its role as a traditional therapeutic target, nor is there evidence of direct drug interactions or use as a biomarker.
