The c.1270C>G (p.R424G) alteration is located in exon 4 (coding exon 4) of the SYNPO2L gene. This alteration results from a C to G substitution at nucleotide position 1270, causing the arginine (R) at amino acid position 424 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
