The c.2324A>C (p.D775A) alteration is located in exon 12 (coding exon 8) of the ZZZ3 gene. This alteration results from a A to C substitution at nucleotide position 2324, causing the aspartic acid (D) at amino acid position 775 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
