Collection Method: clinical testing

The c.628G>A (p.E210K) alteration is located in exon 3 (coding exon 3) of the PSTK gene. This alteration results from a G to A substitution at nucleotide position 628, causing the glutamic acid (E) at amino acid position 210 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
