Mutations in the genes that code for type VI collagen can lead to what are known as the collagenopathies (collagen VI myopathies), such as Bethlem myopathy (BTHLM1), which affect structural tissues like muscles and tendons. We present the case of a young female and her two relatives, who were discovered to share the autosomal dominant COL6A3 mutation and whose presentation in clinic varied from mild to severe. Type VI collagenopathies represent a clinically and genetically heterogeneous spectrum of disorders generally characterized by muscle weakness and joint contractures. We highlight the importance of examining close relatives whenever possible and documenting a …
