Collection Method: clinical testing

The c.745C>A (p.Q249K) alteration is located in exon 5 (coding exon 5) of the TBKBP1 gene. This alteration results from a C to A substitution at nucleotide position 745, causing the glutamine (Q) at amino acid position 249 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
