Ambry Genetics

Dec 28, 2023

The c.1961T>C (p.L654P) alteration is located in exon 13 (coding exon 12) of the EXOC3L1 gene. This alteration results from a T to C substitution at nucleotide position 1961, causing the leucine (L) at amino acid position 654 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
