The c.2198G>A (p.G733E) alteration is located in exon 4 (coding exon 4) of the SYNPO2L gene. This alteration results from a G to A substitution at nucleotide position 2198, causing the glycine (G) at amino acid position 733 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
