Hi. My son has been diagnosed with Oculocutaneous Albinism, and is now being seen by a genetics counsellor who requires mine and his fathers DNA to test the genes we have, and therefore understand better the genes passed to him to give him this condition. I understand enough that me and his father both carry a gene that led to us having a 1:4 chance of having a child with Albinism, and a 1:2 chance they would be a carrier. (Please correct me if i'm wrong!) :-) We had 2 sons, one has Oculocutaneous Albinism and the other doesn't. My question is from my father wanting to know how I got the gene? Did it mean both my parents had the abnormal gene and passed it on...or just one of them? I have 2 full sisters, and my dad has multiple children (my half siblings), none of which show any signs of Albinism. He firstly wondered if I was actually his child or the milkmans ( mum says i'm not ha ha! ), and then corrected himself and asked if he should let all his other kids know they may be a carrier of the gene. Also, could my son who shows no symptoms be a carrier? Our next appointment is not until the summer, so i'm really trying to understand the path to why I carry the gene before then........ TIA
