Collection Method:clinical testing

The c.1423G>T (p.V475L) alteration is located in exon 13 (coding exon 12) of the PTPN5 gene. This alteration results from a G to T substitution at nucleotide position 1423, causing the valine (V) at amino acid position 475 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
