Description

The MT-ATP6 c.467T>G variant was identified in an individual with retinitis pigmentosa with a presumed mitochondrial inheritance pattern. Through a review of available evidence we were able to apply the following criteria: PS3, PS4, PP1. Based on this evidence we have classified this variant as Pathogenic.
