Collection Method: clinical testing

The c.1630C>G (p.L544V) alteration is located in exon 10 (coding exon 9) of the SH2D3A gene. This alteration results from a C to G substitution at nucleotide position 1630, causing the leucine (L) at amino acid position 544 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
