It usually presents within the first decade of life. The most common presenting complaint is primarily myalgia, followed by ‘rippling muscles’ and proximal muscle weakness [ 68 ]. [content.iospress.com]
It is also noteworthy that diabetes mellitus type II (DM II) was present in all five patients older than 45 years. Nevertheless, DM II was also present in three unaffected individuals in this family ( Figure 1, II-1, III-4, III-11). [doi.org]

Etiology
Background Autosomal recessive limb-girdle muscular dystrophies (LGMD2) include a number of disorders with heterogeneous etiology that cause predominantly weakness and wasting of the shoulder and pelvic girdle muscles. [paperity.org]
