The c.496G>A (p.E166K) alteration is located in exon 2 (coding exon 1) of the PSKH1 gene. This alteration results from a G to A substitution at nucleotide position 496, causing the glutamic acid (E) at amino acid position 166 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
