Ambry Genetics

Aug 08, 2022

The c.580G>A (p.G194R) alteration is located in exon 2 (coding exon 2) of the LMOD2 gene. This alteration results from a G to A substitution at nucleotide position 580, causing the glycine (G) at amino acid position 194 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
