CNGB3 mutations cause severe rod dysfunction.

Abstract excerpt

PURPOSE: Congenital achromatopsia or rod monochromatism is a rare autosomal recessive condition defined by a severe loss of cone photoreceptor function in which rods purportedly retain normal or near-to-normal function. This report describes the results of electroretinography in two siblings with CNGB3-associated achromatopsia. METHODS: Full field light- and dark-adapted electroretinograms (ERGs) were recorded...
