Albinism

I'm working on a series of short stories involving a character that I've had for a while now. Her names Sakura, she's Japanese and has low melanin. I know melanin is what causes people to have eye color, skin color and hair color. When I started writing her I used that as the reasons she had grayish eyes, pale skin and grey patches of hair. However as I got older a friend of mine pointed out that really I needed a better reason. I wanted to stick with using low melanin as the reason for her odd coloring. In my search for a medical reasoning for this I came across ocular and oculocutaneous albinism. My three questions are one as albinism is hereditary does that mean that its impossible for neither parent nor grandparent to show signs of albinism when the child does and two I decided to use oculocutaneous albinism type 4 as the form of albinism she has but I haven't found any site that has the signs of oculocutaneous albinism type 4. I would use oculocutaneous albinism tpye 1a but oculocutaneous albinism type 4 is more common in Japanese people than oculocutaneous albinism type 1a is.

So in short my questions are:
Is it impossible for neither parent nor grandparent to show signs of albinism when the child has?
What are the symptoms of oculocutaneous albinism type 4?
Would it really matter if I used oculocutaneous albinism type 1a instead of oculocutaneous albinism type 4 even though type 4 is more common in people of Japanese decent?
