Aceruloplasminemia (ACP) is a rare disorder of iron overload resulting from ceruloplasmin (CP) variants. Because of its rarity and heterogeneity, the diagnosis of ACP is often missed or misdiagnosed. Here, we aim to present a clinical spectrum of ACP and raise more attention to the early diagnosis. Whole exome sequencing (WES) was performed in a Chinese female patient suspected with ACP and her clinical data were collected in detail. The PubMed databases was searched for published ACP patients within the last decade, and we present a systematic review of their clinical features with data extracted from these researches. A novel pathogenic variant (c.2689delC) and a known pathogenic variant (c.606dupA) within ceruloplasmin gene were identified in our patient and confirmed the diagnosis of ACP. Then we reviewed 51 ACP patients including the case we reported here. A possible timeline of symptoms was discovered, anemia appears first (29.7 years old on average), followed by diabetes (37.3 years old) and finally neurological symptoms (50.7 years old). The delay in diagnosis was significantly shortened in patients without neurological symptoms. Biochemical triad including anemia, low to undetectable serum ceruloplasmin, low serum iron and/or hyperferritinemia, showed better sensitivity in diagnosis than clinical triad including diabetes, neurological symptoms, and retinal degeneration. Due to the variable symptom spectrum, patients with ACP often visit different departments, which can lead to misdiagnosis. Clinical attention needs to be paid to symptoms and tests that have a warning effect. Prompt diagnosis in the early stage of the disease can be beneficial.
