Collection Method:clinical testing

The c.1180G>C (p.A394P) alteration is located in exon 8 (coding exon 8) of the DDI2 gene. This alteration results from a G to C substitution at nucleotide position 1180, causing the alanine (A) at amino acid position 394 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
