Ambry Genetics

Feb 22, 2023

The c.97G>A (p.A33T) alteration is located in exon 4 (coding exon 3) of the IFI27L1 gene. This alteration results from a G to A substitution at nucleotide position 97, causing the alanine (A) at amino acid position 33 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
