Ambry Genetics

Apr 07, 2023

The c.56T>A (p.L19H) alteration is located in exon 2 (coding exon 1) of the IFI44L gene. This alteration results from a T to A substitution at nucleotide position 56, causing the leucine (L) at amino acid position 19 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
