The c.2004C>G (p.D668E) alteration is located in exon 10 (coding exon 4) of the ZNF45 gene. This alteration results from a C to G substitution at nucleotide position 2004, causing the aspartic acid (D) at amino acid position 668 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
