Albinism is an inherited condition present at birth, characterized by a lack of melanin that normally gives color to the skin, hair, and eyes. Many types of albinism exist, all of which involve lack of pigment in varying degrees. The condition, which is found in all races, may be accompanied by eye problems and may lead to skin cancer later in life.

• 1 in 20,000 people affected• Inherited recessive alleles from

both parents• Not gender or race specific • More common in some ethnic

groups due to genes differing slightly among different races

Albinistic Girl From Honduras

• There are many alterations of genes• ALL affect production of melanin• Melanin gives hair, skin, and eyes

color• Lack of melanin means lack of color

Lack of melanin give his hair a pale blonde color

• Melanin protects skin from sun damage• Albinoids are vulnerable to sun

damage and dryness due to their lack of melanin• Heavy duty sunscreen and

protective clothing reduce sun damage

Albinoids often wear hats for sun protection

• Vision problems plague Albinoids • Eyes require pigment to function

and focus properly • Lack of pigment in the eye make

the iris translucent, exposing the veins, giving the eye a red or pink color

Albinoids red eye, due to lack of melanin

• Albinoids have underdeveloped optical systems• Many albinoids are “legally blind”• Strong glasses and contact lenses

can help to some degree, though vision problems still occur

Overlapping nerves cause vision problems.

• No cure for Albinism • Temporary treatments such as eye

surgeries have helped• Albinoids reduce skin damage by

dressing appropriately and wearing sun screen.

Albinism is one of the few genetic disorders that affect

all species. All species have melanin, so all can have

Albinism.
