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]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -7 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.0963566).
BS1
Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.0000336 (47/1397944) while in subpopulation NFE AF = 0.0000417 (45/1078752). AF 95% confidence interval is 0.0000318. There are 0 homozygotes in GnomAdExome4. There are 20 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
BS2
High AC in GnomAdExome4 at 47 AD gene.

The c.46G>A (p.G16R) alteration is located in exon 1 (coding exon 1) of the SH3BP2 gene. This alteration results from a G to A substitution at nucleotide position 46, causing the glycine (G) at amino acid position 16 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
