Neuberg Centre For Genomic Medicine, NCGM RCV004785845 SCV005400908 likely pathogenic Congenital stationary night blindness 1B 2023-06-22 criteria provided, single submitter clinical testing The observed stop gained c.2560C>T(p.Arg854Ter) variant in GRM6 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. This variant is reported with the allele frequency of 0.0008% in the gnomAD Exomes. This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. Loss of function variants have been previously reported to be disease causing. Computational evidence (MutationTaster - Disease causing automatic) predicts damaging effect on protein structure and function for this variant. For these reasons, this variant has been classified as Likely Pathogenic. In the absence of variant status in spouse, the molecular diagnosis is not confirmed.
