Research
SCA-12 was identified in 1999. Since then 98 papers have carried it in their title. All of them are listed here, year by year, each linked to its source.

The shape of the field
For two decades after SCA-12 was named, a handful of papers appeared each year. Since 2021 that has changed markedly. For a condition this rare, a rising line is the most hopeful thing on this page.
How understanding developed
The chart shows how much was published. This is the short version of what changed.
1999
SCA-12 was described as a distinct form of spinocerebellar ataxia and linked to an expanded CAG repeat in the PPP2R2B gene on chromosome 5. This is what made it possible to identify SCA-12 specifically, rather than grouping it with other ataxias.
Holmes et al., Nature Genetics, 19992000s
Reports from Indian centres established that SCA-12, while rare worldwide, accounts for a meaningful share of inherited ataxia diagnoses in parts of North India. Much of the clinical description of SCA-12 comes from this work.
Srivastava et al., Annals of Neurology, 2001Today
Cohort studies and review articles continue to sharpen the picture of how SCA-12 presents, how it progresses, and how it differs from other ataxias. The full publication library below tracks what has been published, year by year.
The library
Every paper indexed in PubMed whose title names SCA-12 or the PPP2R2B gene, newest first, compiled on 7 September 2026. Papers PubMed does not index are added by hand and marked as such. Listing a paper is not an endorsement of anything it discusses.
Wider reading
The same search returns 187 further papers whose titles name neither SCA-12 nor PPP2R2B. Some study the gene in other diseases; some mention SCA-12 once, in a list of ataxias. They are kept for completeness, but SCA-12 is not their subject.
Who works on this
SCA-12 is studied by a small number of groups worldwide, with a significant share of the clinical literature coming from centres in India.

Getting involved
Progress in rare conditions depends on participation. Any opportunity is worth reviewing carefully for its purpose, what it asks of you, its risks, and its ethics approval.
