Description

The c.680C>T (p.P227L) alteration is located in exon 9 (coding exon 9) of the TK2 gene. This alteration results from a C to T substitution at nucleotide position 680, causing the proline (P) at amino acid position 227 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
