The c.1216G>A (p.E406K) alteration is located in exon 11 (coding exon 10) of the PTPN5 gene. This alteration results from a G to A substitution at nucleotide position 1216, causing the glutamic acid (E) at amino acid position 406 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
