The c.457A>C (p.K153Q) alteration is located in exon 6 (coding exon 5) of the SPC25 gene. This alteration results from a A to C substitution at nucleotide position 457, causing the lysine (K) at amino acid position 153 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
