Genes affected

SH2D3C (HGNC:16884): (SH2 domain containing 3C) This gene encodes an adaptor protein and member of a cytoplasmic protein family involved in cell migration. The encoded protein contains a putative Src homology 2 (SH2) domain and guanine nucleotide exchange factor-like domain which allows this signaling protein to form a complex with scaffolding protein Crk-associated substrate. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2011]

The c.2497C>A (p.Q833K) alteration is located in exon 12 (coding exon 12) of the SH2D3C gene. This alteration results from a C to A substitution at nucleotide position 2497, causing the glutamine (Q) at amino acid position 833 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
