The c.1231A>G (p.K411E) alteration is located in exon 11 (coding exon 10) of the PRRC2C gene. This alteration results from a A to G substitution at nucleotide position 1231, causing the lysine (K) at amino acid position 411 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
