Variants in the ZNF469 gene in families with Brittle cornea syndrome and keratoconus.

ABSTRACT:

Background

Brittle cornea syndrome 1 (BCS1) is a rare autosomal recessive disorder characterized by corneal and sclera thinning and fragility that is caused by zinc finger protein 469 (ZNF469) gene mutation. Keratoconus is another disease related to corneal thinning. Several reports have linked ZNF469 variants and keratoconus. We recruited a four-generation BCS1 family and two keratoconus families to explore pathogenic ZNF469 variants.

Methods

This study included 11 members from a family with BCS1, 2 families with keratoconus, 368 sporadic keratoconus patients and 325 unrelated healthy controls. Whole exome sequencing of DNA from peripheral blood and cross species conservation analysis was used to investigate and verify ZNF469 variants.
