Albinism is an extremely rare (1:17,000 people) human autosomal recessive condition. Therefore only occurs in phenotype if two alleles coding for Albinism are present within a person.
Albinism is when a lack of pigment is present within the skin (hypopigmentation). When a human has Albinism their melanosomes (contained within the melanocytes) do not allow the movement of the pigment into the extracellular space. As a result the pigment cannot be uptaken by Keratinocytes and such there is a lack of pigment within the skin[1].
