Ambry Genetics

Apr 07, 2023

The c.2899G>C (p.G967R) alteration is located in exon 23 (coding exon 22) of the MYOM3 gene. This alteration results from a G to C substitution at nucleotide position 2899, causing the glycine (G) at amino acid position 967 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
