Detailed explanation-1: -Albinism is a group of heritable conditions associated with decreased or absent melanin in ectoderm-derived tissues (most notably the skin, hair, and eyes), yielding a characteristic decrease in skin pigmentation.
Detailed explanation-2: -A lack of P protein disrupts the production of melanin, leading to the characteristic features of albinism.
Detailed explanation-3: -Albinism affects the production of melanin, the pigment that colours skin, hair and eyes. It’s a lifelong condition, but it does not get worse over time. People with albinism have a reduced amount of melanin, or no melanin at all. This can affect their colouring and their eyesight.
Detailed explanation-4: -Albinism consists of a group of inherited abnormalities of melanin synthesis and are typically characterized by a congenital reduction or absence of melanin pigment. Albinism results from defective production of melanin from tyrosine through a complex pathway of metabolic reactions.
Detailed explanation-5: -Albinism is a rare genetic disorder where you aren’t born with the usual amount of melanin pigment. Melanin is a chemical in your body that determines the color of your skin, hair and eyes. Most people with albinism have very pale skin, hair and eyes.
