Ambry Genetics

Feb 21, 2024

The c.601C>G (p.R201G) alteration is located in exon 5 (coding exon 4) of the MPG gene. This alteration results from a C to G substitution at nucleotide position 601, causing the arginine (R) at amino acid position 201 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
