The c.2690C>A (p.A897D) alteration is located in exon 11 (coding exon 11) of the ZC3H3 gene. This alteration results from a C to A substitution at nucleotide position 2690, causing the alanine (A) at amino acid position 897 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
