rs1064039, also known as G73A, Ala25Thr or A25T, is a variant in the cystatin C CST3 gene.
A relatively small study (167 patients) concluded that rs1064039(A;A) genotypes had about a 3 fold increase in risk for exudative age-related macular degeneration (ARMD).[PMID 11815350

A meta-analysis of 2,410 cases and 2,539 controls reported that although the rs1064039(A) allele is associated with about a 1.5x increased odds ratio for developing Alzheimer's disease in Caucasians, no increased risk was seen in Asians.[PMID 22435454]
