The c.1027A>C (p.K343Q) alteration is located in exon 11 (coding exon 10) of the PSIP1 gene. This alteration results from a A to C substitution at nucleotide position 1027, causing the lysine (K) at amino acid position 343 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
