Ambry Genetics

Oct 06, 2021

The c.833C>T (p.A278V) alteration is located in exon 9 (coding exon 9) of the TMEM87A gene. This alteration results from a C to T substitution at nucleotide position 833, causing the alanine (A) at amino acid position 278 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
