The c.509A>G (p.E170G) alteration is located in exon 4 (coding exon 4) of the SH3BGR gene. This alteration results from a A to G substitution at nucleotide position 509, causing the glutamic acid (E) at amino acid position 170 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
