Genes affected

SH2D1B (HGNC:30416): (SH2 domain containing 1B) By binding phosphotyrosines through its free SRC (MIM 190090) homology-2 (SH2) domain, EAT2 regulates signal transduction through receptors expressed on the surface of antigen-presenting cells (Morra et al., 2001 [PubMed 11689425]).[supplied by OMIM, Mar 2008]

Ambry Genetics

Feb 13, 2024

The c.197A>G (p.Q66R) alteration is located in exon 2 (coding exon 2) of the SH2D1B gene. This alteration results from a A to G substitution at nucleotide position 197, causing the glutamine (Q) at amino acid position 66 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
