The c.1792C>T (p.P598S) alteration is located in exon 1 (coding exon 1) of the MTUS2 gene. This alteration results from a C to T substitution at nucleotide position 1792, causing the proline (P) at amino acid position 598 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
