Description

Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Identified in individuals with retinal dystrophy in published literature and referred for genetic testing at GeneDx who also harbored a second GUCY2D variant, although segregation information was not provided for all cases (Liu et al., 2020; Hahn et al., 2022); This variant is associated with the following publications: (PMID: 35314386, 32821499)
