The c.313A>G (p.R105G) alteration is located in exon 2 (coding exon 1) of the ZSCAN20 gene. This alteration results from a A to G substitution at nucleotide position 313, causing the arginine (R) at amino acid position 105 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
