Neuberg Centre For Genomic Medicine, NCGM RCV004771665 SCV005382328 likely pathogenic Ullrich congenital muscular dystrophy 1A 2023-05-20 criteria provided, single submitter clinical testing Ullrich congenital muscular dystrophy-1 (UCMD1) can be caused by homozygous, compound heterozygous, or heterozygous mutation in COL6A2 gene. Ullrich congenital muscular dystrophy is characterized by generalized muscle weakness and striking hypermobility of distal joints in conjunction with variable contractures of more proximal joints and normal intelligence. Additional findings may include kyphoscoliosis, protruded calcanei, and follicular hyperkeratosis. Some patients manifest at birth and never achieve independent ambulation, whereas others maintain ambulation into adulthood. Progressive scoliosis and deterioration of respiratory function is a typical feature (Kirschner, 2013). The gene is also associated with AR inheritance pattern of Ullrich congenital muscular dystrophy-1. Results of parental testing will help confirm inheritance pattern as well as diagnosis.
