The c.1342C>G (p.Q448E) alteration is located in exon 8 (coding exon 7) of the SH2D3A gene. This alteration results from a C to G substitution at nucleotide position 1342, causing the glutamine (Q) at amino acid position 448 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
