The c.532C>G (p.P178A) alteration is located in exon 4 (coding exon 3) of the ZNF774 gene. This alteration results from a C to G substitution at nucleotide position 532, causing the proline (P) at amino acid position 178 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
