一家系2例先天性红细胞生成性卟啉病并文献复习
Two siblings with congenital erythropoietic porphyria in one family: case report and literature review
例1,女,7岁;例2,男(例1胞弟),3岁。2例患儿均在出生后出现粉红色尿,光照部位(颜面部、双手)出现皮肤水疱,继而破溃、结痂、瘢痕形成,关节挛缩导致活动障碍等临床表现。2例患儿基因检测均为UROS基因c.776T>C(p.Leu259Pro)纯合变异,确诊为UROS基因变异常染色体隐性遗传性先天性红细胞生成性卟啉病。该病例报道提示,对于不明原因婴幼儿期溶血性贫血、粉红色尿、严重光敏性皮炎者,应考虑先天性红细胞生成性卟啉病可能,尽早完善基因检测,提早干预治疗改善预后。
Case 1 was a 7-year-old girl; Case 2 was her 3-year-old younger brother. Both children developed pink urine shortly after birth and exhibited blistering on photo-exposed areas (face and hands), followed by ulceration, crusting, scarring, and joint contractures leading to impaired mobility. Genetic testing in both patients identified a homozygous variant in the UROS gene, c.776T>C (p.Leu259Pro), confirming autosomal recessive congenital erythropoietic porphyria due to UROS mutations. This case report highlights that congenital erythropoietic porphyria should be considered in infants and young children with unexplained hemolytic anemia, pink urine, and severe photosensitive dermatitis. Early genetic testing is recommended to facilitate timely intervention and improve outcomes.
