Dec 07, 2021
Ambry Genetics
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.448G>A (p.V150M) alteration is located in exon 4 (coding exon 4) of the TDRD9 gene. This alteration results from a G to A substitution at nucleotide position 448, causing the valine (V) at amino acid position 150 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
