ABSTRACT:Historical events have shaped the various regional gene pools of the French-Canadian (FC) population, leading to increased prevalence of some rare diseases. The first studies of these founder effects were performed in large part by astute clinicians such as André Barbeau. In collaboration with others, he contributed greatly to the delineation of phenotypic subtypes of these conditions. As such, the following neurogenetic disorders were first identified in patients of FC origin: AOA2, ARSACS, HSAN2, RAB, and HMSN/ACC. We have summarized our current knowledge of the main hereditary ataxias, spastic parapareses and neuropathies that are particular to the FC population. The initial genetic characterization of the more common and homogeneous of these diseases has been largely completed. We predict that the regional populations of Canada will allow the identification of new rare forms of hereditary ataxias, spastic parapareses and neuropathies, and contribute to the unravelling of the genetic basis of these entities.

Abstract:Background:The growing number of spastic ataxia of Charlevoix-Saguenay (SACS) gene mutations reported worldwide has broadened the clinical phenotype of autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS). The identification of Quebec ARSACS cases without two knownSACSmutation led to the development of a multi-modal genomic strategy to uncover mutations in this large gene and explore phenotype variability.Methods:Search forSACSmutations by combining various methods on 20 cases with a classical French-Canadian ARSACS phenotype without two mutations and a group of 104 sporadic or recessive spastic ataxia cases of unknown cause. Western blot on lymphoblast protein from cases with different genotypes was probed to establish if they still expressed sacsin.Results:A total of 12 mutations, including 7 novels, were uncovered in Quebec ARSACS cases. The screening of 104 spastic ataxia cases of unknown cause for 98SACSmutations did not uncover carriers of two mutations. Compounds heterozygotes for one missenseSACSmutation were found to minimally express sacsin.Conclusions:The large number ofSACSmutations present even in Quebec suggests that the size of the gene alone may explain the great genotypic diversity. This study does not support an expanding ARSACS phenotype in the French-Canadian population. Most mutations lead to loss of function, though phenotypic variability in other populations may reflect partial loss of function with preservation of some sacsin expression. Our results also highlight the challenge ofSACSmutation screening and the necessity to develop new generation sequencing methods to ensure low cost complete gene sequencing.

Background and PurposeThe purposes of this methodological study were to adapt the European Heart Failure Self-care Behaviour Scale-9 to the French–Canadian population and to evaluate its reliability.MethodsThe adaptation process consisted of translation, back-translation, evaluation by an expert committee, and pretesting. Reliability was evaluated with stability criteria (test–retest) and internal consistency.ResultsPretesting led to testing of two response formats: 5-point Likert scale and the frequency scale. Both demonstrated good levels of agreement between the test–retest, although the values were higher with the frequency format. The Cronbach's alpha coefficients ranged from 0.71 to 0.78 (Likert scale) and 0.70 to 0.83 (frequency scale).ConclusionThe French–Canadian version of the EHFScB-9, in both formats, demonstrated good evidence of reliability.
