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 کاملFine mapping of "mini-muscle," a recessive mutation causing reduced hindlimb muscle mass in mice.
Prolonged selective breeding of Hsd:ICR mice for high levels of voluntary wheel running has favored an unusual phenotype (mini-muscle [MM]), apparently caused by a single Mendelian recessive allele, in which hindlimb muscle mass is reduced by almost 50%. We recently described the creation and phenotypic characterization of a population suitable for mapping the genomic location of the MM gene. S...
متن کاملAutosomal Recessive Nonsyndromic Hearing Loss: A Case Report with a Mutation in TRIOBP Gene
Hearing loss (HL) is the most common sensory defect. Various genetic as well as environmental factors have been shown to contribute in it. More than 100 loci have been recognized to cause autosomal recessive nonsyndromic hearing loss (ARNSHL). Here, we report a 6-year old female patient with bilateral pre-lingual HL in whom a mutation has been identified in TRIOBP gene (c.6362C>T, S2121L). In s...
متن کاملA novel GJA8 mutation causing a recessive triangular cataract
PURPOSE The aim of the study was to characterize the underlying mutation in a consanguineous family having cataracts. METHODS Family D having congenital cataracts was treated at the University Eye Clinics at Giessen (Germany). Lens material from surgeries was collected, immediately frozen at -80 degrees C, and used for cDNA production. Blood was taken from the proband and available family mem...
متن کاملA novel keratocan mutation causing autosomal recessive cornea plana.
PURPOSE Mutations in keratocan (KERA), a small leucine-rich proteoglycan, have recently been shown to be responsible for cases of autosomal recessive cornea plana (CNA2). A consanguineous pedigree in which cornea plana cosegregated with microphthalmia was investigated by linkage analysis and direct sequencing. METHODS Linkage was sought to polymorphic microsatellite markers distributed around...
