Collection Method: clinical testing

The c.704A>G (p.E235G) alteration is located in exon 5 (coding exon 5) of the SH2D4B gene. This alteration results from a A to G substitution at nucleotide position 704, causing the glutamic acid (E) at amino acid position 235 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
