OCA5

Albinism, Oculocutaneous, Type V

Clinical Characteristics
Ocular Features: 

The phenotype in the two families studied includes photophobia, nystagmus, foveal hypoplasia and decreased visual acuity.  The fundus is hypopigmented.

Systemic Features: 

The hair is golden-colored and the skin is described as white. 

Genetics

The specific gene causing this form of oculocutaneous albinism has not been identified.  However, an area of homozygosity in the region of 4q24 has been identified in 6 members in two families belonging to a large consanguineous Pakistani pedigree in which it segregates with the OCA5 phenotype. 

Pedigree: 
Autosomal recessive
Treatment
Treatment Options: 

No treatment is available for oculocutaneous albinism but appropriately tinted glasses could be beneficial.
