Molecular analysis of red cell disorders has revolutionized diagnosis, however, there remain challenges.
This patient presented with hemolytic anemia in the newborn period. He required chronic transfusions to maintain his hemoglobin level until 6 years of age. A splenectomy was performed at 3 years of age.
Using whole genome sequencing, we were able to identify a duplication upstream of the red cell promoter of . Long-read RNA sequencing established aberrant expression off of this promoter.
These non-coding variants remain challenging to identify. His promoter duplication may have a founder effect in South Asia.
红细胞疾病的分子分析彻底改变了诊断方式，然而，仍存在挑战。
该患者在新生儿期出现溶血性贫血。他需要长期输血以维持血红蛋白水平，直至6岁。3岁时进行了脾切除术。
通过全基因组测序，我们能够鉴定出红细胞启动子上游的一段重复序列。长读长RNA测序确定了该启动子的异常表达。
这些非编码变异仍难以识别。他的启动子重复序列可能在南亚具有奠基者效应。
