Novel homozygous nonsynonymous variant of CNNM4 gene in a Chinese family with Jalili syndrome.

ABSTRACT: Jalili syndrome (JS) is a rare autosomal-recessive inherited disorder characterized by cone-rod dystrophy and amelogenesis imperfecta. It is often misdiagnosed in clinical practice due to its heterogeneity and rarity. Two JS patients from a consanguineous family were included in this study. Detailed ophthalmic examinations were performed. Oral photography was taken. The DNA sample of the proband was sequenced using the customized capture panel, which includes 338 retinal disease genes. Sanger sequencing was performed for validation and segregation. The patients had poor vision, photophobia, and nystagmus from childhood. Fundus examination revealed diffused chorioretinal atrophy with a prominent macular coloboma. OCT showed a deep staphyloma, severely reduced retinal thickness, retinoschisi
