Collection Method:clinical testing

The c.1480G>A (p.V494I) alteration is located in exon 13 (coding exon 12) of the PTPN5 gene. This alteration results from a G to A substitution at nucleotide position 1480, causing the valine (V) at amino acid position 494 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
