Albinism is not related to blood type; it is related to genetics. Albinism is a skin and appendage disorder caused by a deficiency or reduced function of tyrosinase. It is somewhat related to hereditary factors, and also to the lack or synthesis obstruction of melanin. If both parents pass the pathogenic gene they carry to their children, then the children may develop this type of albinism. Ocular albinism is usually an X-linked recessive genetic disorder, mainly transmitted from mothers carrying the albinism gene to their sons, leading to the onset of the disease. Albinism is not directly related to blood type. If albinism occurs, it is advisable to consult and treat at a hospital, and to take preventive measures against the disease before pregnancy.
