Cohen syndrome (CS) is a rare autosomal recessive inherited condition characterized by pathological changes affecting multiple systems. The extensive clinical variability associated with CS poses a significant diagnostic challenge. Additionally, there is limited documentation on the co-occurrence of CS with psychiatric symptoms.
We report a case of a 30-year-old patient exhibiting characteristic physical features and psychiatric symptoms. Whole exome sequencing identified two heterozygous variants, a nonsense variation c.4336 C > T and a missense mutation c.4729G > A. Integrating clinical manifestations with genetic test results, we established the diagnosis of CS combined with psychiatric symptoms.
This case introduces a novel missense variant as a candidate in the expanding array of VPS13B pathogenic variants. Its clinical significance remains unknown, and further investigation may broaden the spectrum of pathogenic variants associated with the VPS13B gene. Early diagnosis of CS is crucial for the prognosis of young children and holds significant importance for their families.
Cohen 综合征(CS)是一种罕见的常染色体隐性遗传性疾病,其特征为多系统病变。CS 广泛的临床变异性给诊断带来了极大的挑战。此外,CS 合并精神症状的报道也很少。
我们报告了一例 30 岁患者,其表现出典型的体格特征和精神症状。全外显子组测序发现了两个杂合变异,无义变异 c.4336C>T 和错义突变 c.4729G>A。综合临床表现和基因检测结果,我们诊断为 CS 合并精神症状。
本病例介绍了一个新的错义变异作为 VPS13B 致病性变异的候选者。其临床意义尚不清楚,进一步的研究可能会扩大与 VPS13B 基因相关的致病性变异谱。早期诊断 CS 对婴幼儿的预后至关重要,对其家庭也具有重要意义。
