STR: CACNA1A_SCA6_CAG was marked as current diagnostic
Added comment: NM_023035.2:c.6929_6931CAG[X]
PolyQ expansion alters gene binding, impairs transcription factor function, and is toxic to cells expressing the α1ACT – effects consistent with a loss of function
Normal: ≤18 repeats
Questionable significance: 19 CAG repeats
Full penetrance: ≥20 repeats

Ataxia v0.212 CACNA1A Bryony Thompson Classified gene: CACNA1A as Green List (high evidence)
Ataxia v0.212 CACNA1A Bryony Thompson Added comment: Comment on list classification: Ataxia can be caused by a triplet repeat expansion in this gene, which is not detectable with current WES/WGS technologies. However, SNVs have also been reported as disease-causing.
