The c.1469G>T (p.R490M) alteration is located in exon 10 (coding exon 9) of the TSTD2 gene. This alteration results from a G to T substitution at nucleotide position 1469, causing the arginine (R) at amino acid position 490 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
