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 -15 ACMG points.

BP4
?
    BP4 - Multiple lines of computational evidence suggest no impact on gene or gene product (conservation, evolutionary, splicing impact, etc.)
Computational evidence support a benign effect (BayesDel_noAF=-0.51).
BP6
?
    BP6 - Reputable source recently reports variant as benign, but the evidence is not available to the laboratory to perform an independent evaluation
Variant 4-2820623-G-A is Benign according to our data. Variant chr4-2820623-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 751413.Status of the report is criteria_provided_single_submitter, 1 stars.
BP7
?
    BP7 - A synonymous (silent) variant for which splicing prediction algorithms predict no impact to the splice consensus sequence nor the creation of a new splice site AND the nucleotide is not highly conserved
Synonymous conserved (PhyloP=0.313 with no splicing effect.
BS1
?
    BS1 - Allele frequency is greater than expected for disorder
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0000525 (8/152314) while in subpopulation AFR AF= 0.0000962 (4/41562). AF 95% confidence interval is 0.0000324. There are 0 homozygotes in gnomad4. There are 4 alleles in male gnomad4 subpopulation. Median coverage is 34. This position pass quality control queck.
BS2
?
    BS2 - Observed in a healthy adult individual for a recessive (homozygous), dominant (heterozygous), or X-linked (hemizygous) disorder, with full penetrance expected at an early age
High AC in GnomAd at 8 AD gene.
