The c.980A>G (p.N327S) alteration is located in exon 3 (coding exon 3) of the PARD6G gene. This alteration results from a A to G substitution at nucleotide position 980, causing the asparagine (N) at amino acid position 327 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
