Collection Method:clinical testing

The c.827C>T (p.P276L) alteration is located in exon 9 (coding exon 9) of the AK8 gene. This alteration results from a C to T substitution at nucleotide position 827, causing the proline (P) at amino acid position 276 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
