TYR and albinism: In this study, we screened 172 patients with classical ocular signs of albinism (nystagmus, macular hypoplasia, and hypopigmentation of the fundus) for sequence variants in TYR, OCA2, GPR143, and MC1R. Here, we describe the prevalence of sequence variants of the analyzed genes in different albinism phenotypes and report a set of novel sequence variants.
