Collection Method:clinical testing

The c.49G>T (p.G17C) alteration is located in exon 1 (coding exon 1) of the TDRD9 gene. This alteration results from a G to T substitution at nucleotide position 49, causing the glycine (G) at amino acid position 17 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
