The c.342A>C (p.E114D) alteration is located in exon 2 (coding exon 1) of the ZSCAN9 gene. This alteration results from a A to C substitution at nucleotide position 342, causing the glutamic acid (E) at amino acid position 114 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
