Albinism is a genetic condition that a person is born with. It is not something that develops over time, can be caught, or can be cured. A person with albinism has no or decreased melanin production. Melanin is the pigment responsible for skin, hair, and eye color. Because melanin also plays a critical role in how the eyes develop in utero, most people with albinism experience some degree of vision challenges alongside their lighter coloring. Albinism is more common than many people realize, affecting people of every race and ethnicity all around the world.
In most types of albinism, a child must inherit a changed gene from both parents in order to have albinism. This means that two parents who do not have albinism themselves can still have a child who does, because both parents can carry the gene without showing any signs of it.
There are several different types of albinism, each caused by changes in different genes. Oculocutaneous albinism, or OCA, is the most common and affects the skin, hair, and eyes. There are multiple subtypes (OCA1, OCA2, OCA3, and OCA4, among others), and they vary in how much melanin the body is able to produce. For example, someone with OCA1 may produce very little to no melanin at all, resulting in white hair and very fair skin, while someone with OCA2 or OCA3 may have slightly more pigment and a wider range of hair and skin tones. Ocular albinism, or OA, primarily affects the eyes with little to no visible differences in skin and hair color, and is more common in males.
Visual impairment is one of the most significant aspects of living with albinism, and it is important to understand why. Because melanin plays such a vital role in how the eyes develop, a deficiency in its production can affect how well the eyes form and how they communicate with the brain. This can lead to things like sensitivity to light, involuntary eye movement, and difficulty with depth perception. Vision challenges can range from mild visual impairment all the way to legal blindness, and every person’s experience is different. Many people with albinism use glasses, contacts, or other visual aids to help them navigate daily life.
But albinism is so much more than a medical definition. It is a lived experience, and it looks different for every single person who has it. No two people with albinism are exactly alike, and that is part of what makes this community so worth understanding. Albinism does not define what a person can do, dream, or become. It is simply one part of who we are.
