The c.3425A>G (p.N1142S) alteration is located in exon 12 (coding exon 11) of the IGSF3 gene. This alteration results from a A to G substitution at nucleotide position 3425, causing the asparagine (N) at amino acid position 1142 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
