Description

The PLP1 c.83G>A variant is predicted to result in the amino acid substitution p.Gly28Glu. To our knowledge, this variant has not been reported in the literature or in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. Two alternate missense changes at the same amino acid position have been reported in affected individuals; however, the significance of these other missense alterations is also uncertain (p.Gly28Val, p.Gly28Arg, Grossi et al. 2011. PubMed ID: 21679407; Duan et al. 2022. PubMed ID: 35346287). Although we suspect that this variant may be pathogenic, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
