CHARGE syndrome Uncertain:1
This sequence change replaces glutamine, which is neutral and polar, with glutamic acid, which is acidic and polar, at codon 435 of the SEMA3E protein (p.Gln435Glu). This variant is present in population databases (rs752774852, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with SEMA3E-related conditions. ClinVar contains an entry for this variant (Variation ID: 529115). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt SEMA3E protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
SEMA3E-related disorder Uncertain:1
The SEMA3E c.1303C>G variant is predicted to result in the amino acid substitution p.Gln435Glu. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.014% of alleles in individuals of Latino descent in gnomAD, which may be too common to be a primary cause of disease. Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
