The c.574G>A (p.E192K) alteration is located in exon 3 (coding exon 2) of the ZSCAN22 gene. This alteration results from a G to A substitution at nucleotide position 574, causing the glutamic acid (E) at amino acid position 192 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
