GeneDx RCV000727132 SCV000569017 uncertain significance not provided 2016-06-21 criteria provided, single submitter clinical testing A variant of uncertain significance has been identified in the CLN3 gene. The c.-1 G>T variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. It was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The c.-1 G>T variant alters a position that is not conserved in the Kozak sequence, which plays a role in the initiation of protein translation. Additionally, to our knowledge, no regulatory variants have been reported in the CLN3 gene in association with juvenile neuronal ceroid lipofuscinosis (Stenson et al., 2014). However, in the absence of RNA/functional studies, the actual effect of the c.-1 G>T variant in this individual is uncertain. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant.
