Collection Method: clinical testing

The c.469G>A (p.V157I) alteration is located in exon 4 (coding exon 4) of the TPD52 gene. This alteration results from a G to A substitution at nucleotide position 469, causing the valine (V) at amino acid position 157 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
