摘要

Microcephaly with or without chorioretinopathy, lymphedema or mental retardation is a rare KIF11-related disorder. Here we report the case of a patient with microcephaly, lymphedema, nystagmus and familial exudative vitreoretinopathy carrying a novel de novo KIF11 nonsense variant (NM_004523.4:p.Glu123Ter), which is considered pathogenic. This case expands the phenotypic range of KIF11 pathogenic variants and highlights the importance of early ophthalmological evaluation, genetic counseling and family assessment.
