The c.742G>A (p.E248K) alteration is located in exon 2 (coding exon 1) of the ZNF652 gene. This alteration results from a G to A substitution at nucleotide position 742, causing the glutamic acid (E) at amino acid position 248 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
