The c.202G>A (p.A68T) alteration is located in exon 2 (coding exon 1) of the ZSCAN22 gene. This alteration results from a G to A substitution at nucleotide position 202, causing the alanine (A) at amino acid position 68 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
