Retinitis Pigmentosa 81

Clinical Characteristics
Ocular Features: 

Patients often complain of night vision problems before the age of 5 years.  Fundus changes of optic nerve pallor, retinal vessel attenuation, and bone spicule pigmentary clumping in the midperiphery are evident by the third decade of life.  Progressive RPE and choroidal atrophy in the macula have been described and may be progressive.  ERG responses are absent from at least 28 years of age.

Systemic Features: 

No systemic abnormalities have been reported.

Genetics

One consanguineous Pakistani family containing 9 affected members with retinal degeneration has been reported.  Homozygosity of a missense mutation in the IFT43 gene (14q24.3) was found in 4 affected sibs.

Treatment
Treatment Options: 

No treatment has been reported.
