Sex-linked recessive congenital ataxia.
A family is reported in which three boys, two full brothers and a half brother, presented with marked delay in motor milestones, severe limb and truncal ataxia, nystagmus, speech delay and moderate global retardation. Autosomal recessive and sex linked recessive forms of cerebellar hypoplasia are reviewed and it is suggested that this family may have a rare, if not unique, form of sex-linked ce...
متن کاملNovel compound heterozygous mutation in SACS gene leads to a milder autosomal recessive spastic ataxia of Charlevoix‐Saguenay, ARSACS, in a Finnish family
Autosomal recessive spastic ataxia of Charlevoix-Saguenay is a rare disorder outside Quebec causing childhood-onset cerebellar ataxia, peripheral neuropathy, and pyramidal tract signs. A Finnish family with milder form of ARSACS was found to harbor three mutations, p.E1100K, p.N1489S, and p.M1359T, in SACS gene. The mutations segregated with the disease.
متن کاملContribution of Somatic and Dendritic SK Channels in the Firing Rate of Deep Cerebellar Nuclei: Implication in Cerebellar Ataxia
Introduction: Loss of inhibitory output from Purkinje cells leads to hyperexcitability of the Deep Cerebellar Nuclei (DCN), which results in cerebellar ataxia. Also, inhibition of small-conductancecalcium-activated potassium (SK) channel increases firing rate f DCN, which could cause cerebellar ataxia. Therefore, SK channel activators can be effective in reducing the symptoms of this disease, ...
متن کاملPhenotypic features and genetic findings in sacsin-related autosomal recessive ataxia in Tunisia.
BACKGROUND Autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) is a clinically homogenous disorder reported in Quebec caused by mutations in the SACS gene (chromosome 13q12). Recently, we identified a Tunisian kindred demonstrating linkage to the ARSACS locus. OBJECTIVE To report clinical, neurophysiological, and nerve biopsy findings in patients with autosomal recessive cerebe...
متن کاملComplications of Implant Rehabilitation in Ectodermal Dysplasia Patients: A Review Study
Background and Aim: Ectodermal dysplasia (ED) is a hereditary disease that affects ectodermal tissues. Its oral manifestations include hypodontia or oligodontia, which cause the reduction of the height and width of the alveolar ridge. Considering numerous difficulties that these patients encounter with regard to facial appearance, talking, and chewing, their rehabilitation has a major influence...
