The c.205C>G (p.P69A) alteration is located in exon 3 (coding exon 3) of the TMEM260 gene. This alteration results from a C to G substitution at nucleotide position 205, causing the proline (P) at amino acid position 69 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
