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 made for transcript

Verdict is Benign. Variant got -9 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.061558843).

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00171 (252/147416) while in subpopulation AFR AF= 0.00571 (234/40978). AF 95% confidence interval is 0.00511. There are 1 homozygotes in gnomad4. There are 114 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAd4 at 252 AD gene.

Collection Method: clinical testing

The c.76G>A (p.G26R) 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 76, causing the glycine (G) at amino acid position 26 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
