Collection Method: clinical testing

The c.1159A>G (p.K387E) alteration is located in exon 10 (coding exon 9) of the PRRC2C gene. This alteration results from a A to G substitution at nucleotide position 1159, causing the lysine (K) at amino acid position 387 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
