The c.973C>T (p.P325S) alteration is located in exon 10 (coding exon 9) of the MAMSTR gene. This alteration results from a C to T substitution at nucleotide position 973, causing the proline (P) at amino acid position 325 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
