Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.

[EX Q]: Question: Do apolipoprotein E genotypes influence the age of onset in Huntington 's disease?
Answer: The ApoE genotype does not affect the course of HD significantly.
[EX A]: no

[EX Q]: Question: Does transient ischemia limit subsequent ischemic regional dysfunction in humans : a transesophageal echocardiographic study during minimally invasive coronary artery bypass surgery?
Answer: Ischemic dysfunction was precipitated by the 5-min LAD occlusion, as shown by the increase in LVWMS and pulmonary artery pressure. However, a 5-min coronary occlusion and the resulting ischemia do not alter regional left ventricular systolic function during subsequent ischemia in humans.
[EX A]: no

[EX Q]: Question: Does epigenome-wide DNA methylation assay reveal placental epigenetic markers for noninvasive fetal single-nucleotide polymorphism genotyping in maternal plasma?
Answer: The present studies systematically identified hypermethylated sites in fetal tissues and preliminarily demonstrated that some of the fetal epigenetic markers that contain informative SNPs have great potential for noninvasive fetal genetic diagnosis.
[EX A]:
yes
