Ambry Genetics

Sep 26, 2022

The c.502G>A (p.A168T) alteration is located in exon 4 (coding exon 3) of the TMEM219 gene. This alteration results from a G to A substitution at nucleotide position 502, causing the alanine (A) at amino acid position 168 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
