The c.359G>C (p.C120S) alteration is located in exon 3 (coding exon 3) of the RBM48 gene. This alteration results from a G to C substitution at nucleotide position 359, causing the cysteine (C) at amino acid position 120 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

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 not expected to disrupt RBM48 protein function. This variant has not been reported in the literature in individuals affected with RBM48-related conditions. This variant is present in population databases (rs376509478, gnomAD 0.01%). This sequence change replaces cysteine, which is neutral and slightly polar, with serine, which is neutral and polar, at codon 120 of the RBM48 protein (p.Cys120Ser). -
