Summaries for FRG1 Gene

Entrez Gene Summary for FRG1 Gene

  • This gene maps to a location 100 kb centromeric of the repeat units on chromosome 4q35 which are deleted in facioscapulohumeral muscular dystrophy (FSHD). It is evolutionarily conserved and has related sequences on multiple human chromosomes but DNA sequence analysis did not reveal any homology to known genes. In vivo studies demonstrate the encoded protein is localized to the nucleolus. [provided by RefSeq, Jul 2008]

GeneCards Summary for FRG1 Gene

Disorders for FRG1 Gene


  • Facioscapulohumeral muscular dystrophy 1 (FSHD1) [MIM:158900]: A degenerative muscle disease characterized by slowly progressive weakness of the muscles of the face, upper-arm, and shoulder girdle. The onset of symptoms usually occurs in the first or second decade of life. Affected individuals usually present with impairment of upper extremity elevation. This tends to be followed by facial weakness, primarily involving the orbicularis oris and orbicularis oculi muscles. {ECO:0000269 PubMed:16341202, ECO:0000269 PubMed:23720823}. Note=The gene represented in this entry may be involved in disease pathogenesis. Overexpression of human FRG1 in mice leads to development of facioscapulohumeral muscular dystrophy (FSHD1)-like symptoms such as kyphosis, progressive muscle dystrophy and skeletal muscle atrophy (PubMed:16341202). It also causes aberrant pre-mRNA splicing of TNNT3 and MTMR1, affects the localization and activity of SUV420H1, and leads to increased levels of EID3, resulting in inhibited muscle differentiation (PubMed:23720823). These results suggest that FSHD1 results from inappropriate overexpression of FRG1 which leads to abnormal alternative splicing of specific pre-mRNAs. {ECO:0000269 PubMed:16341202, ECO:0000269 PubMed:23720823}.
