The c.518T>C (p.L173P) alteration is located in exon 4 (coding exon 4) of the MXRA7 gene. This alteration results from a T to C substitution at nucleotide position 518, causing the leucine (L) at amino acid position 173 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
