The c.932A>G (p.N311S) alteration is located in exon 9 (coding exon 9) of the COPS2 gene. This alteration results from a A to G substitution at nucleotide position 932, causing the asparagine (N) at amino acid position 311 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
