Pollen food allergy syndrome (PFAS) related to PR10 from vegetables is common in northern Europe, whereas in Mediterranean countries PFAS has been preferentially associated with profilins. However, there are pollen‐allergic patients reactive to Bet v 1 in birch‐free regions. Since it cannot be the primary sensitizer, there has to be another culprit. Quercus ilex is a good candidate as it belongs to the order Fagales. This order includes trees with highly sensitizing pollen such as alder, hazel, hornbeam, oak and chestnut because of the presence of PR10 allergens. PR10 allergens have indeed been described in other Quercus species.

Quercus ilex 花粉过敏原，Que i 1，负责西班牙过敏患者因水果引起的花粉食物过敏综合征

与来自蔬菜的 PR10 相关的花粉食物过敏综合征 (PFAS) 在北欧很常见，而在地中海国家，PFAS 优先与 profilins 相关。然而，在无桦树地区​​有对 Bet v 1 有反应的花粉过敏患者。既然它不可能是主要的敏化剂，那么肯定还有另一个罪魁祸首。Quercus ilex 是一个很好的候选者，因为它属于 Fagales 目。由于存在 PR10 过敏原，该订单包括具有高度致敏花粉的树木，如桤木、榛树、角树、橡树和板栗。PR10 过敏原确实在其他栎属物种中有所描述。
