Ambry Genetics

Jun 11, 2024

The c.1290G>T (p.E430D) alteration is located in exon 11 (coding exon 11) of the NARFL gene. This alteration results from a G to T substitution at nucleotide position 1290, causing the glutamic acid (E) at amino acid position 430 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
