Ambry Genetics

Sep 25, 2023

The c.1970C>T (p.P657L) alteration is located in exon 11 (coding exon 11) of the MAGI3 gene. This alteration results from a C to T substitution at nucleotide position 1970, causing the proline (P) at amino acid position 657 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
