Mutations in the non-coding RNA gene RNU4ATAC are associated with growth restriction and complications related to antibody deficiency. Here, we report that innate immune dysfunction is a previously unrecognised feature of this disorder. In particular, painful chilblain-like lesions are common in RNU4ATAC patients and are linked to dysregulated type I interferon signalling.
非编码RNA基因RNU4ATAC的突变与生长受限及抗体缺陷相关并发症有关。在此，我们报告先天性免疫功能障碍是该疾病此前未被认识到的一个特征。特别是，冻疮样疼痛性皮损在RNU4ATAC患者中很常见，且与I型干扰素信号失调有关。
