Ambry Genetics

Nov 10, 2022

The c.461C>A (p.P154Q) alteration is located in exon 5 (coding exon 2) of the KSR1 gene. This alteration results from a C to A substitution at nucleotide position 461, causing the proline (P) at amino acid position 154 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
