Muscle-eye-brain disease is a congenital muscular dystrophy with eye and brain involvement due to POMGnT1 mutations.
To describe the clinical and molecular features of 3 Italian patients with POMGnT1 mutations.
Case reports.
One patient had muscle and brain abnormalities without eye involvement. Two patients had a classic muscle-eye-brain disease phenotype with different levels of clinical severity.
Brain magnetic resonance imaging showed cortical malformation and posterior fossa involvement. Immunofluorescence for glycosylated alpha-dystroglycan performed on muscle biopsy specimens demonstrated an absent signal in 1 patient and reduced staining in 2 patients. Molecular analysis identified 5 mutations, 2 of which are novel.
This article adds to what is known about the genotype-phenotype correlation and expands our awareness of the clinical spectrum associated with POMGnT1 mutations.
肌-眼-脑病是一种由于POMGnT1基因突变导致的伴有眼部和脑部病变的先天性肌营养不良症。
描述3例携带POMGnT1基因突变的意大利患者的临床和分子特征。
病例报告。
1例患者有肌肉和脑部异常，但无眼部受累。2例患者具有典型的肌-眼-脑疾病表型，临床严重程度不同。
脑磁共振成像显示皮质畸形和后颅窝受累。对肌肉活检标本进行的糖基化α- dystroglycan免疫荧光检测显示，1例患者信号缺失，2例患者染色减少。分子分析鉴定出5种突变，其中2种为新突变。
本文补充了关于基因型-表型相关性的已知信息，并扩展了我们对与POMGnT1突变相关的临床谱的认识。
