Could albinism be prenatally detected?

Yes for most types. Several varieties of albinism exist, and prenatal diagnosis is available for most of them.
Yes. There are several ways to diagnose albinism prenatally. Most diagnoses are made by either dna analysis looking for the mutations which most commonly cause albinism. Another method is to take a skin biopsy from the fetus. A pathologist can then determine whether there is normal development of melanocytes, the cells which give our skin pigment. Prenatal diagnosis is only done rarely for albinism.
