Different from classical autosomal recessive Wolfram syndrome, Wolfram-like syndrome is an autosomal dominant disorder caused by a heterozygous mutation in the WFS1 gene. In this case, a 7-year-old male child presented to the eye clinic due to vision loss that could not be corrected, discovered during a routine examination. The child had experienced hearing impairment since early childhood, leading to cochlear implantation. Ophthalmic examination revealed optic disc atrophy in both eyes. Optical coherence tomography imaging demonstrated a distinctive thickening of the outer plexiform layer with abnormal layering, characteristic of a single mutation in the WFS1 gene. Subsequent genetic testing identified a de novo heterozygous missense mutation c.2051C>T (p.A684V) in the WFS1 gene, which ultimately led to the diagnosis of Wolfram-like syndrome.
与经典的常染色体隐性Wolfram综合征不同,Wolfram-like综合征是一种由WFS1基因单个杂合变异引起的常染色体显性疾病。本例7岁男性儿童因体检时发现视力无法矫正来眼科就诊。患儿自幼听力差,行人工耳蜗植入术。眼科检查发现双眼视神经萎缩,其中相干光层析成像术(OCT)可见WFS1基因单一变异所特有的双眼外网状层增厚且结构异常分层。进一步行基因检测,患者WFS1基因单个杂合错义变异c.2051C>T(p.A684V),父母均未携带该变异,最终诊断为Wolfram-like综合征。.
