Background:

Albinism is one of the earliest recognized human genetic diseases.
Its molecular pathogenesis was poorly understood until recently.

Purpose of the Study:

To elucidate the molecular mechanisms underlying albinism.
To highlight the role of genetic mutations in albinism.

Main Methods:

Analysis of mutations in seven key genes involved in melanin biosynthesis.
Correlating genotype with phenotypic features.

Main Results:

Mutations in at least seven genes reduce melanin pigment biosynthesis.
Clinical features include hypopigmentation, optic nerve misrouting, and reduced visual acuity.

Conclusions:

A broad phenotypic spectrum is associated with albinism.
Molecular analysis is essential for accurate albinism diagnosis.
