A DLST genotype associated with reduced risk for Alzheimer’s disease

Abstract
Article abstract Recent studies suggest that variants of the DLST gene alter the risk of AD. DLST encodes the core subunit of the mitochondrial α-ketoglutarate dehydrogenase complex, which is deficient in AD. The authors report that in 247 US white subjects, homozygosity for DLST A19,117, T19,183 was associated with a reduced risk of AD (odds ratio [OR] = 0.35, p = 0.018). The reduced risk was marked in subjects who did not carry the apolipoprotein (APOE)-4 allele (OR = 0.16, p = 0.014). Further study of DLST in AD appears warranted.
