The c.787A>C (p.T263P) alteration is located in exon 3 (coding exon 3) of the PARM1 gene. This alteration results from a A to C substitution at nucleotide position 787, causing the threonine (T) at amino acid position 263 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
