The c.80A>G (p.N27S) alteration is located in exon 2 (coding exon 2) of the ZPBP2 gene. This alteration results from a A to G substitution at nucleotide position 80, causing the asparagine (N) at amino acid position 27 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
