Genes affected

STAM2 (HGNC:11358): (signal transducing adaptor molecule 2) The protein encoded by this gene is closely related to STAM, an adaptor protein involved in the downstream signaling of cytokine receptors, both of which contain a SH3 domain and the immunoreceptor tyrosine-based activation motif (ITAM). Similar to STAM, this protein acts downstream of JAK kinases, and is phosphorylated in response to cytokine stimulation. This protein and STAM thus are thought to exhibit compensatory effects on the signaling pathway downstream of JAK kinases upon cytokine stimulation. [provided by RefSeq, Jul 2008]

The c.840G>T (p.E280D) alteration is located in exon 9 (coding exon 9) of the STAM2 gene. This alteration results from a G to T substitution at nucleotide position 840, causing the glutamic acid (E) at amino acid position 280 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
