CPSF1 mutations are associated with early-onset high myopia and involved in retinal ganglion cell axon projection.

ABSTRACT: High myopia is a severe form of nearsightedness, which can result in blindness due to its associated complications. While both genetic and environmental factors can cause high myopia, early-onset high myopia (eoHM), which is defined as high myopia that occurs before school age, is considered to be caused mainly by genetic variations, with minimal environmental involvement. Here we report six rare heterozygous loss-of-function (LoF) variants in CPSF1 that were identified in six of 623 probands with eoHM but none of 2657 probands with other forms of genetic eye diseases; this difference was statistically significant (P = 4.60 × 10-5, Fisher's exact test). The six variants, which were confirmed by Sanger sequencing, were c.3862_3871dup (p.F1291*), c.2823_2824del (p.V943Lfs*65), c.1858C>T (p.Q
