Abstract excerpt
PURPOSE: A hallmark of the IMPDH1-related rod-cone dystrophy is the highly variable expressivity. Disease onset, severity and progression are variant-dependent due to specific affected photoreceptor mechanisms, underscoring the importance of genotype-phenotype correlations. We provide a detailed clinical characterization of a patient with rod-cone dystrophy caused by a rare de novo missense IMPDH1 variant. CASE...
