The c.1225C>G (p.P409A) alteration is located in exon 9 (coding exon 8) of the TMEM184A gene. This alteration results from a C to G substitution at nucleotide position 1225, causing the proline (P) at amino acid position 409 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
