Task: Answer Verification
Input (English): Question: Is genetic polymorphism in exon 2 of cathepsin D associated with vascular dementia?
Answer: The major genotype frequency at CTSD C224T in normal controls was higher in the Asian population than in various European populations. Our study does not show a significant difference in genotype (P=0.3071) and allele (P=0.2291) frequencies of CTSD C224T between VaD and normal controls. This was the first genetic association study of CTSD in a VaD population.
Output (English): no
