GeneDx RCV000478883 SCV000573636 uncertain significance not provided 2017-03-03 criteria provided, single submitter clinical testing The c.310 T>G variant in the HEXA gene has not been reported previously as a pathogenic variant, nor as a benignvariant, to our knowledge. This variant is not observed in large population cohorts (Lek et al., 2016; 1000 GenomesConsortium et al., 2015; Exome Variant Server). In-silico splice prediction models predict that c.310 T>G may createa cryptic splice donor site upstream to the natural splice donor site of intron 2. However, in the absence ofRNA/functional studies, the actual effect of the c.310 T>G change in this individual is unknown. If c.310 T>G doesnot alter splicing, it will result in the C104G missense change. The C104G variant is a non-conservative amino acidsubstitution, which occurs at a position that is conserved across species. In silico analysis predicts this variant isprobably damaging to the protein structure/function. We interpret c.310 T>G as a variant of uncertain significance.
