The c.368C>G (p.P123R) alteration is located in exon 6 (coding exon 5) of the TMEM104 gene. This alteration results from a C to G substitution at nucleotide position 368, causing the proline (P) at amino acid position 123 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
