A Novel Missense Mutation in CLCN1 Gene in a Family with Autosomal Recessive Congenital Myotonia
Congenital recessive myotonia is a rare genetic disorder caused by mutations in CLCN1, which codes for the main skeletal muscle chloride channel ClC-1. More than 120 mutations have been found in this gene. The main feature of this disorder is muscle membrane hyperexcitability. Here, we report a 59-year male patient suffering from congenital myotonia. He had transient generalized myotonia, which...
متن کاملA Novel Mutation in CLCN1 Associated with Feline Myotonia Congenita
Myotonia congenita (MC) is a skeletal muscle channelopathy characterized by inability of the muscle to relax following voluntary contraction. Worldwide population prevalence in humans is 1:100,000. Studies in mice, dogs, humans and goats confirmed myotonia associated with functional defects in chloride channels and mutations in a skeletal muscle chloride channel (CLCN1). CLCN1 encodes for the m...
متن کاملMyotonia congenita (Becker's variant).
A 21 year old right handed male resident of Bihar presented with 4 years history of gradual onset progressive st i f fness in both thighs and calves which improves on continued activity along with hypertrophy of muscles of all the limbs and dimpling on hitting over thigh and hands. He also has history of inability to walk fast or run and delayed opening of left eye after forceful closure of bot...
متن کاملSyndromic Intellectual Disability Caused by a Novel Truncating Variant in AHDC1: A Case Report
Mutations in the AHDC1 gene are associated with the Xia-Gibbs syndrome (XGS), a sporadic genetic disorder characterised by developmental delay, intellectual disability, hypotonia, obstructive sleep apnoea, dysmorphic facial features, and cerebral malformations with plagiocephaly. Here we report the case of a 13-year-old Colombian female patient with a history of developmental delay, speech dela...
متن کاملNovel Mutations in the CLCN1 Gene of Myotonia Congenita: 2 Case Reports
INTRODUCTION Myotonia Congenita is an inherited myotonia that is due to a mutation in the skeletal muscle chloride channel CLCN1. These mutations lead to reduced sarcolemmal chloride conductance, causing delayed muscle relaxation that is evident as clinical and electrical myotonia. METHODS We report the clinical presentations of two individuals with Myotonia Congenita (MC). RESULTS Patient ...
