Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.340G>A (p.G114S) alteration is located in exon 3 (coding exon 3) of the RBM48 gene. This alteration results from a G to A substitution at nucleotide position 340, causing the glycine (G) at amino acid position 114 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant is present in population databases (rs368019384, gnomAD 0.09%), and has an allele count higher than expected for a pathogenic variant. This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 114 of the RBM48 protein (p.Gly114Ser). This variant has not been reported in the literature in individuals affected with RBM48-related conditions. 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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt RBM48 protein function. ClinVar contains an entry for this variant (Variation ID: 1979802). -
