ATP1A2 mutations in 11 families with familial hemiplegic migraine.
2005
Abstract Familial hemiplegic migraine (FHM) is an autosomal dominant form of migraine with aura. The disease is caused by mutations of at least three genes among which two have been identified, CACNA1A and ATP1A2. Very few mutations have been identified so far in ATP1A2. We screened the coding sequence of ATP1A2 in 26 unrelated FHM probands in whom CACNA1A screening was negative. A total of eight different mutations were identified in 11 of the probands (41%), including six missense mutations, one small deletion leading to a frameshift, and one in frame deletion. All were novel mutations. Two mutations were recurrent, in three and two families, respectively. Genotyping of 94 relatives of th…
Exome sequencing in congenital ataxia identifies two new candidate genes and highlights a pathophysiological link between some congenital ataxias and…

To investigate the genetic basis of congenital ataxias (CAs), a unique group of cerebellar ataxias with a nonprogressive course, in 20 patients from consanguineous families, and to identify new CA genes. Singleton -exome sequencing on these 20 well-clinically characterized CA patients. We first checked for rare homozygous pathogenic variants, then, for variants from a list of genes known to be associated with CA or very early-onset ataxia, regardless of their mode of inheritance. Our replication cohort of 180 CA patients was used to validate the new CA genes. We identified a causal gene in 16/20 families: six known CA genes (7 patients); four genes previously implicated in another neurologi…
