I have one son with albinism and one without. My husband is white, I am Indian (i.e., South Asian). The effect of my son's albinism is NOT "white skin, white hair, pale eyes" but instead he has dark blond hair, dark blue-grey eyes, and pale skin but no paler than my Anglo-heritage husband. He would not look out of place at a family reunion on my husband's side.
Neither I nor my husband have any (known) relatives with albinism. My question is how can it be that nobody--literally NOBODY--in either of our families has any record of there being relatives with albinism? In my husband's family, maybe they could have "passed," especially if their coloring was more like my son's. But in my family, there's just no way they would have gone unnoticed!
