We present a 56-year-old female with a history of carbohydrate intolerance and ketotic hypoglycemia, dysmorphic features, mild developmental delay, lymphedema, altered pain sensation, and frequent fractures, who was found to have a heterozygous 8.09 Mb deletion of chromosome 8q24.11q24.13 containing more than 39 genes, as well as a duplication of 20q11.23 containing one gene. The deleted region overlaps that of two previously reported patients, who share a subset of clinical characteristics with the patient described here. Some of this patient's clinical features are consistent with the loss of genes in the deleted region. The diagnostic work-up of this patient clearly demonstrates the evolution of genetic testing techniques.
我们报告了一例 56 岁女性病例,其病史包括碳水化合物不耐受和酮症低血糖、畸形特征、轻度发育迟缓、淋巴水肿、疼痛感觉改变和频繁骨折,该患者被发现存在 8q24.11q24.13 染色体上的 8.09Mb 杂合性缺失,包含超过 39 个基因,以及 20q11.23 上的一个基因重复。缺失区域与之前报道的两名患者重叠,这两名患者与本病例描述的患者有部分临床特征相似。该患者的一些临床特征与缺失区域内基因的缺失相一致。该患者的诊断过程清楚地展示了遗传检测技术的发展演变。
