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]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.939

The c.131T>A (p.V44D) alteration is located in exon 1 (coding exon 1) of the SH2D1B gene. This alteration results from a T to A substitution at nucleotide position 131, causing the valine (V) at amino acid position 44 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
