Collection Method: clinical testing

The c.544C>A (p.Q182K) alteration is located in exon 5 (coding exon 4) of the SH2D4A gene. This alteration results from a C to A substitution at nucleotide position 544, causing the glutamine (Q) at amino acid position 182 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
