The c.359T>C (p.V120A) alteration is located in exon 3 (coding exon 3) of the PKN3 gene. This alteration results from a T to C substitution at nucleotide position 359, causing the valine (V) at amino acid position 120 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
