The c.962A>T (p.D321V) alteration is located in exon 1 (coding exon 1) of the MTUS2 gene. This alteration results from a A to T substitution at nucleotide position 962, causing the aspartic acid (D) at amino acid position 321 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
