Dysphagia has not been reported in genetically confirmed limb-girdle muscular dystrophy type 2B (LGMD2B). A 40-year-old woman reported exercise-induced calf pain at age 34, followed by progressive lower and upper limb weakness. At age 38, progressive dysphagia for solids, and subsequently liquids, ensued. Endoscopic and videofluoroscopic-radiological findings indicated a myopathic swallowing disorder. Molecular genetic analysis confirmed two dysferlin gene mutations consistent with a compound heterozygote state. Progressive dysphagia should be considered as part of the expanding dysferlinopathy phenotype.
尚未有报道称遗传性肢带型肌营养不良 2B 型(LGMD2B)患者会出现吞咽困难。一位 40 岁的女性在 34 岁时报告出现运动诱发的小腿疼痛,随后逐渐出现下肢和上肢无力。在 38 岁时,她逐渐出现固体食物吞咽困难,随后液体也难以吞咽。内镜和透视放射性检查结果提示肌病性吞咽障碍。分子遗传学分析证实存在两种 dysferlin 基因突变,符合复合杂合状态。进行性吞咽困难应被视为扩展型 dysferlinopathy 表型的一部分。
