Figure 1From: Autosomal recessive spastic ataxia of Charlevoix Saguenay (ARSACS): expanding the genetic, clinical and imaging spectrumSACS mutations. Graphical overview of mutations found in this and other studies (Human Gene Mutation database, except gross deletions). Different mutation types are marked with different symbols: missense mutations = squares; insertions/duplications = triangles with downward orientation; deletions = triangles with upward orientation. Sequence variations identified in this study are coloured, with the colour indicating the pathogenicity class: red = pathogenic, orange = likely pathogenic, yellow = uncertain. Known protein domains of the sacsin protein are highlighted in green. AA = amino acid; HGMD = Human Gene Mutation Database.Back to article page
