Genes affected

SH2D2A (HGNC:10821): (SH2 domain containing 2A) This gene encodes an adaptor protein thought to function in T-cell signal transduction. A related protein in mouse is responsible for the activation of lymphocyte-specific protein-tyrosine kinase and functions in downstream signaling. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2010]

The c.806T>A (p.V269D) alteration is located in exon 7 (coding exon 7) of the SH2D2A gene. This alteration results from a T to A substitution at nucleotide position 806, causing the valine (V) at amino acid position 269 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
