The c.2942A>G (p.N981S) alteration is located in exon 11 (coding exon 10) of the IGSF3 gene. This alteration results from a A to G substitution at nucleotide position 2942, causing the asparagine (N) at amino acid position 981 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
