Collection Method: clinical testing

The c.272C>G (p.P91R) alteration is located in exon 2 (coding exon 1) of the TATDN2 gene. This alteration results from a C to G substitution at nucleotide position 272, causing the proline (P) at amino acid position 91 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
