Absence of melanin. We could say that this is the fundamental fact.Albinism is a genetic condition that affects the pigmentation of skin and hair eyes, originated for a small mutation of the genes, resulting in the absence of melanin, but why does it arise? For us to be born with albinism, there must be a subtle chance: that both our father and our mother have this recessive gene.
For those of us who are not albinos, the melanocytes fulfill their function by transforming the amino acid tyrosine into melanin and this, is distributed almost "magically", giving us a distinctive skin color (capable of protecting us from solar radiation in turn) and a certain shade for our eyes and our hair.If we cannot produce this substance, or it occurs at a very low level, hypopigmentation appears.It is also important that we make a small "appreciation." There are several types of albinism, there are those who, for example, can have very clear eyes but not blond hair.So, not all albinos have a complete hypopigmentation in all its features.
