Ambry Genetics

Aug 08, 2023

The c.452C>T (p.P151L) alteration is located in exon 4 (coding exon 3) of the C1QTNF9 gene. This alteration results from a C to T substitution at nucleotide position 452, causing the proline (P) at amino acid position 151 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
