Abstract
Limb-girdle muscular dystrophy was first introduced in the 1950s as a distinct family of unusual genetic diseases. The prevalence of the disease is about 4-7/1000, with a spectrum of onset at different ages. LGMD has a cluster of symptoms varying in severity and presentation in patients. Limb-girdle muscular dystrophy`s inheritance is unique as it can be autosomal dominant or recessive. We report a young boy with autosomal recessive limb-girdle muscular dystrophy (LGMD), presented with distal muscle weakness in all four limbs for three years and thinning of legs, arms, and thighs. Our gene of focus is TTN, which is associated with muscle elasticity and myogenesis. Our subtype reported is currently associated with a new homozygous TTN variant; thus, we are writing a novel variant mutation causing limb-girdle muscular dystrophy type 10.
