Ambry Genetics

May 27, 2022

The c.257G>A (p.R86Q) alteration is located in exon 4 (coding exon 3) of the TRPT1 gene. This alteration results from a G to A substitution at nucleotide position 257, causing the arginine (R) at amino acid position 86 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
