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 کاملIdentification of a novel splice-site mutation in the Lebercilin (LCA5) gene causing Leber congenital amaurosis
PURPOSE Leber congenital amaurosis (LCA) is one of the most common causes of hereditary blindness in infants. To date, mutations in 13 known genes and at two other loci have been implicated in LCA causation. An examination of the known genes highlights several processes which, when defective, cause LCA, including photoreceptor development and maintenance, phototransduction, vitamin A metabolism...
متن کاملNovel TULP1 mutation causing leber congenital amaurosis or early onset retinal degeneration.
PURPOSE To report a large, consanguineous Algerian family affected with Leber congenital amaurosis (LCA) or early-onset retinal degeneration (EORD). METHODS All accessible family members underwent a complete ophthalmic examination, and blood was obtained for DNA extraction. Homozygosity mapping was performed with markers flanking 12 loci associated with LCA. The 15 exons of TULP1 were sequenc...

متن کاملNovel GUCY2D Gene Mutations in Japanese Male Twins with Leber Congenital Amaurosis
Purpose. Leber congenital amaurosis (LCA), a genetically and clinically heterogeneous disease, is the earliest onset retinitis pigmentosa (RP) and is the most severe of hereditary retinal dystrophies. This study was conducted to investigate genetic and clinical features of LCA in a set of Japanese male twins with LCA. Methods. To identify causative mutations, 74 genes known to cause RP or LCA w...
