NARP syndrome

People with NARP (Neuropathy, Ataxia and Retinitis Pigmentosa) syndrome have neurological (muscle weakness, epilepsy and memory problems) and balance problems in addition to retinitis pigmentosa.

Retinal degeneration can be one feature of a genetic condition that also affects other body systems. Certain genetic faults that cause damage to the eye can also impact other organs and tissues. Where more than one body system is involved, the condition is called a syndrome. However, the sight loss aspect can be very similar to that experienced by people living with non-syndromic retinitis pigmentosa.

This condition is inherited by maternal transmission – it is passed on by women to both their sons and daughters. Males tend to be more affected than females.

NARP syndrome is caused by mutation in the gene MTATP6.
