Ambry Genetics

Feb 28, 2024

The c.508A>G (p.M170V) alteration is located in exon 7 (coding exon 7) of the TMEM87A gene. This alteration results from a A to G substitution at nucleotide position 508, causing the methionine (M) at amino acid position 170 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
