Involvement in diseasei

Limb-girdle muscular dystrophy 2F (LGMD2F)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionAn autosomal recessive degenerative myopathy initially affecting the proximal limb girdle musculature. Muscle from patients shows a complete loss of delta-sarcoglycan as well as of the others components of the sarcoglycan complex.

Interactioni

Subunit structurei

Interacts with FLNC and DAG1. Cross-link to form 2 major subcomplexes: one consisting of SGCB, SGCD and SGCG and the other consisting of SGCB and SGCD. The association between SGCB and SGCG is particularly strong while SGCA is loosely associated with the other sarcoglycans (By similarity).By similarity
