Proximal upper limb and distal lower limb weakness is also common as well as atrophy of the quadriceps (most commonly), biceps brachii, and lower leg muscles. However, calf hypertrophy has also been reported in some cases. LGMD2L progresses slowly, with most patients remaining ambulatory until late adulthood. muscular dystrophy, limb-girdle, type 2L DOID:0110284 ANO5 autosomal recessive limb-girdle muscular dystrophy OMIM:611307 LGMD2L MEDGEN:370102 Orphanet:206549 GARD:0012536 MONDO:0012652 MESH:C566968 limb-girdle muscular dystrophy type 2L autosomal recessive limb-girdle muscular dystrophy caused by mutation in ANO5 autosomal recessive limb-girdle muscular dystrophy obsolete_autosomal recessive limb-girdle muscular dystrophy type 2L
