Genes affected

SH2B1 (HGNC:30417): (SH2B adaptor protein 1) This gene encodes a member of the SH2-domain containing mediators family. The encoded protein mediates activation of various kinases and may function in cytokine and growth factor receptor signaling and cellular transformation. Alternatively spliced transcript variants have been described. [provided by RefSeq, Mar 2009]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=6.3735247E-4).
• BP6: Variant 16-28871920-A-G is Benign according to our data. Variant chr16-28871920-A-G is described in ClinVar as [Benign]. Clinvar id is 1232867.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.4 is higher than 0.05.
