The c.568G>A (p.E190K) alteration is located in exon 2 (coding exon 2) of the PHAX gene. This alteration results from a G to A substitution at nucleotide position 568, causing the glutamic acid (E) at amino acid position 190 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
