The c.76A>G (p.S26G) alteration is located in exon 2 (coding exon 2) of the TANC2 gene. This alteration results from a A to G substitution at nucleotide position 76, causing the serine (S) at amino acid position 26 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
