The c.554C>A (p.P185Q) alteration is located in exon 6 (coding exon 5) of the ZNF250 gene. This alteration results from a C to A substitution at nucleotide position 554, causing the proline (P) at amino acid position 185 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
