The c.1117C>T (p.P373S) alteration is located in exon 12 (coding exon 12) of the MTA3 gene. This alteration results from a C to T substitution at nucleotide position 1117, causing the proline (P) at amino acid position 373 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
