The c.404A>G (p.E135G) alteration is located in exon 3 (coding exon 3) of the SDF2L1 gene. This alteration results from a A to G substitution at nucleotide position 404, causing the glutamic acid (E) at amino acid position 135 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
