The c.1330G>A (p.G444R) alteration is located in exon 11 (coding exon 11) of the TDRD3 gene. This alteration results from a G to A substitution at nucleotide position 1330, causing the glycine (G) at amino acid position 444 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
