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.833G>A (p.R278H) alteration is located in exon 7 (coding exon 7) of the SH2D2A gene. This alteration results from a G to A substitution at nucleotide position 833, causing the arginine (R) at amino acid position 278 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
