Ambry Genetics

Oct 30, 2023

The c.1219C>A (p.L407I) alteration is located in exon 8 (coding exon 8) of the MXRA8 gene. This alteration results from a C to A substitution at nucleotide position 1219, causing the leucine (L) at amino acid position 407 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
