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]

SH2B1 Gene-Disease associations (from GenCC):

• severe early-onset obesity-insulin resistance syndrome due to SH2B1 deficiency

  Inheritance: AD Classification: MODERATE, SUPPORTIVE Submitted by: Orphanet, Genomics England PanelApp

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.79).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.838 is higher than 0.05.
