New ZNF644 mutations identified in patients with high myopia.

ABSTRACT:

Purpose

Myopia, or near-sightedness, is one of the most common human visual impairments worldwide, and high myopia is one of the leading causes of blindness. In this study, we investigated the mutation spectrum of ZNF644, a causative gene for autosomal dominant high myopia, in a high-myopia cohort from a Chinese population.

Methods

DNA was isolated with the standard proteinase K digestion and phenol-chloroform method from a case cohort of 186 subjects diagnosed with high myopia (spherical refractive error equal or less than -6.00 diopters). Sanger sequencing was performed to find potential mutations in all coding exons, flanking splicing sites, and untranslated regions (UTRs) of ZNF644 (NM_201269). Identified novel variants were further screened in 526 ethnically matched nor
