Common Variants in the TYR Gene with Unclear Pathogenicity as the Cause of Oculocutaneous Albinism in a Cohort of Russian Patients [PDF]

Biomedicines
Background: oculocutaneous albinism (OCA) is a hereditary impairment of skin, hair, and eye pigmentation. The most common form of albinism is autosomal recessive albinism, caused by mutations in the TYR gene, accounting for approximately 40–50% of all ...

Foveal hypoplasia in oculocutaneous albinism: An optical coherence tomography study

African Vision and Eye Health, 2023
Background: Albinism is an inherited condition characterised by a lack of pigmentation. Foveal hypoplasia, which occurs because of disruptions in normal foveal development, is commonly observed in albinism.
