Ambry Genetics

Sep 20, 2023

The c.1014A>T (p.E338D) alteration is located in exon 4 (coding exon 4) of the TRPC7 gene. This alteration results from a A to T substitution at nucleotide position 1014, causing the glutamic acid (E) at amino acid position 338 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
