Genes affected

SH3BP2 (HGNC:10825): (SH3 domain binding protein 2) The protein encoded by this gene has an N-terminal pleckstrin homology (PH) domain, an SH3-binding proline-rich region, and a C-terminal SH2 domain. The protein binds to the SH3 domains of several proteins including the ABL1 and SYK protein tyrosine kinases , and functions as a cytoplasmic adaptor protein to positively regulate transcriptional activity in T, natural killer (NK), and basophilic cells. Mutations in this gene result in cherubism. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2009]

The c.1534C>T (p.R512C) alteration is located in exon 12 (coding exon 11) of the SH3BP2 gene. This alteration results from a C to T substitution at nucleotide position 1534, causing the arginine (R) at amino acid position 512 to be replaced by a cysteine (C). 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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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 SH3BP2 protein function. ClinVar contains an entry for this variant (Variation ID: 577475). This variant has not been reported in the literature in individuals affected with SH3BP2-related conditions. This variant is present in population databases (rs369562627, gnomAD 0.005%). This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 512 of the SH3BP2 protein (p.Arg512Cys). -
