: We report the case of a seven-year-old female from a consanguineous Saudi family with autosomal recessive limb girdle muscular dystrophy type 2D (LGMD2D) most likely caused by a rare SGCA mutation. Histopathological and molecular investigations resulted in the discovery of a homozygous mutation (c.226 C>T (p.L76 F)) in exon 3 of SGCA in the patient. The parents and one sibling were heterozygous carriers, but the mutation was not otherwise detected in 80 ethnic controls from the same geographic area. In silico analysis revealed that the mutation resulted in a functional leucine to phenylalanine alteration that was deleterious to the protein structure. This is only the second reported case of the p.L76F mutation in LGMD, and highlights that molecular genetics analysis is essential to deliver the most appropriate management to the patient and offer the family genetic counseling.
