The c.286A>G (p.S96G) alteration is located in exon 4 (coding exon 4) of the TM9SF4 gene. This alteration results from a A to G substitution at nucleotide position 286, causing the serine (S) at amino acid position 96 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
