Thesis Title:

P/Q-type voltage gated calcium channels and spinocerebellar ataxia type 6

Undergraduate Institution and Major/Degree:

State University of New York at Geneseo

Major Advisor(s):

Christopher Gomez

Research Description:

My current research focuses on voltage-dependent calcium channels (VDCCs) and their role in the pathogenesis of spinocerebellar ataxia type six (SCA6). SCA6 is a dominantly inherited progressive ataxia, which leads to marked cerebellar atrophy and specifically Purkinje cell degeneration. SCA6 is caused by a mutation in the CACNA1A gene, which encodes the pore forming subunit (a1A) of the P/Q-type voltage gated calcium channel. We are currently exploring how the SCA6 mutation alters normal functioning of the a1A subunit and how this mutation can cause cell death as observed in SCA6.
