SLC38A8 and Nystagmus: WGS seeks to screen both coding and noncoding regions of the gene, but only 8 out of 93 (8.6%) variants were found to be noncoding (all were splice‐site mutations); these were found in one cataract patient (HSF4), two nystagmus patients (both FRMD7), and five albinism patients (OCA2 [two patients], GPR143, SLC38A8, and TYR).
