Ambry Genetics

Nov 22, 2023

The c.514C>G (p.R172G) alteration is located in exon 4 (coding exon 4) of the OLFML2A gene. This alteration results from a C to G substitution at nucleotide position 514, causing the arginine (R) at amino acid position 172 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
