What is Delta-Sarcoglycanopathy?

Delta-Sarcoglycanopathy is a rare genetic disorder that affects muscle function. It falls under the category of limb-girdle muscular dystrophies (LGMD). Here are some fascinating facts about this condition.

Delta-Sarcoglycanopathy is caused by mutations in the SGCD gene, which encodes the delta-sarcoglycan protein.
The delta-sarcoglycan protein is part of the sarcoglycan complex, crucial for muscle fiber stability.
Mutations in the SGCD gene lead to muscle weakness and wasting, primarily in the shoulders and hips.
This condition is inherited in an autosomal recessive manner, meaning both parents must carry the mutated gene.
Symptoms usually appear in late childhood or adolescence, but they can also manifest in early adulthood.
Muscle weakness often starts in the pelvic and shoulder girdles, gradually spreading to other muscles.
