[EX Q]: Question: Are fragile histidine triad gene alterations essential for hepatocellular carcinoma development in South Korea?
Answer: Aberrant FHIT transcripts were more common in HCC tissues as compared to non-cancerous liver tissues. However, Fhit expression was lost or reduced in a minor fraction of HCC tissues, while it was strongly expressed in non-cancerous liver tissues. Therefore, our study suggests that FHIT plays a role in relatively few HCC cases in South Korea.
[EX A]: no

[EX Q]: Question: Are filaggrin loss-of-function mutations a predisposing factor for atopic dermatitis in an Ishigaki Island under subtropical climate?
Answer: The FLG loss-of-function mutation frequency was not significantly different between the AD and non-AD groups in a cohort of children from Ishigaki Island, which has a subtropical climate, suggesting that FLG loss-of-function mutations are not always a predisposing factor for AD prevalence.
[EX A]: no
