Limb-Girdle Muscular Dystrophy Type 2i (LGMD2i) – Market Outlook, Epidemiology, Competitive Landscape, and Market Forecast Report – 2023 To 2033

Limb-girdle muscular dystrophies (LGMDs) encompass a set of muscle disorders with varying inheritance patterns, either autosomal dominant (referred to as LGMD type 1) or autosomal recessive (known as LGMD type 2). The fukutin-related protein gene (FKRP; OMIM 606596) plays a significant role in developing both LGMD2I and congenital muscular dystrophy 1C. FKRP transcripts are predominantly expressed in skeletal muscle, the placenta, and the heart. Altered α-dystroglycan protein expression patterns have been observed in muscle biopsies of LGMD2I patients, indirectly suggesting that FKRP, a potential glycosyltransferase, is necessary for post-translational dystroglycan modification. Diagnosis typically concerns the clinical presentation, characterized by proximal muscle wasting and weakness, particularly in the lower limbs. The primary diagnostic criterion involves the identification of two pathogenic variants in the FKRP gene. Creatine kinase levels are usually elevated, exceeding 1,...
