Albanism. Does anyone know any details on how it's passed on?

I'm 37+3 pregnant with a little girl. A thought has suddenly crossed my mind that my little girl could have albanism. My partners Auntie has it, she was passed it down by her mother side so my partners grandmother however she didn't have it as well. Now I'm not in any way saying I am bothered by the fact she could have albanism, I will love my child regardless! But I'm just wondering whether anyone knew anything about it and whether it's passed on through certain generations? I have a midwife appointment Thursday so I will be asking her then.
