Ambry Genetics

Jul 30, 2023

The c.31G>C (p.G11R) alteration is located in exon 1 (coding exon 1) of the MPZL3 gene. This alteration results from a G to C substitution at nucleotide position 31, causing the glycine (G) at amino acid position 11 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
