The c.821A>G (p.Q274R) alteration is located in exon 7 (coding exon 6) of the SH2D4A gene. This alteration results from a A to G substitution at nucleotide position 821, causing the glutamine (Q) at amino acid position 274 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
