The c.814A>G (p.T272A) alteration is located in exon 5 (coding exon 4) of the ZSCAN9 gene. This alteration results from a A to G substitution at nucleotide position 814, causing the threonine (T) at amino acid position 272 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
