The c.184C>G (p.P62A) alteration is located in exon 1 (coding exon 1) of the DBX2 gene. This alteration results from a C to G substitution at nucleotide position 184, causing the proline (P) at amino acid position 62 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
