As mentioned in the Results, although the classic hallmark of FKRP-associated dystroglycanopathies is reduction in functional α-DG glycosylation, several studies have documented that patients with LGMD2R9 displaying the most common mutation c.826C>A (Alhamidi et al., 2017; Lee et al., 2019) and patients with CMD (Louhichi et al., 2004) show variability in the levels of glycosylated α-DG. The gene discussed is FKRP; the disease is neuromuscular disease caused by qualitative or quantitative defects of alpha-dystroglycan.
