label_lc: snupn-related muscular dystrophy with or without multi-system involvement
description: A form of congenital muscular dystrophy in which the cause of the disease is pathogenic variation in the SNUPN gene. The phenotype is typically characterized by a variable degree of muscle weakness, elevated serum creatinine kinase, and myopathic signs in skeletal muscle. Extra-muscular features involving the ocular, skeletal, respiratory, and central nervous system may also be present.
