Ambry Genetics

Nov 23, 2022

The c.220A>G (p.R74G) alteration is located in exon 2 (coding exon 1) of the TMEM187 gene. This alteration results from a A to G substitution at nucleotide position 220, causing the arginine (R) at amino acid position 74 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
