The c.1133A>G (p.N378S) alteration is located in exon 9 (coding exon 9) of the TM9SF3 gene. This alteration results from a A to G substitution at nucleotide position 1133, causing the asparagine (N) at amino acid position 378 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
