Not necessarily— there are several types of albinism, and each affects a different gene. OA is the result of malfunctions in the GPR143 gene. For a child to have OA, the mother must contribute a malfunctioning GPR143 gene, found in the X chromosome. If the baby is female and inherits one normal GPR143 gene and one albinism gene, the normal gene will take over, and the baby’s eyes will produce enough melanin. However, as males only have one X chromosome, they may end up with OA.
