Yes, albinism is considered a genetic abnormality.
Albinism is characterized by a hereditary defect in melanin biosynthesis, resulting in hypopigmentation. While the degree of hypopigmentation can vary, albinism invariably involves deficits in the visual system. Therefore, due to its genetic basis and associated physiological differences, particularly concerning vision and pigmentation, albinism is generally classified as a genetic abnormality. Albinism, while presenting unique challenges, is also a part of human diversity.
