At the standard significance of p < 5 × 10−8 (Table 2, Supplementary Figure S1), CDCA7 in chromosome 2 for esotropia, HLA-F in chromosome 6 for exotropia, and DAB1-AS1 in chromosome 1 for idiopathic superior oblique muscle palsy were suggested as candidates in a GWAS with BBJ (180K). Here, CDCA7 is linked to Exotropia.
