Ambry Genetics

Aug 10, 2021

The c.4553G>A (p.C1518Y) alteration is located in exon 25 (coding exon 25) of the LTN1 gene. This alteration results from a G to A substitution at nucleotide position 4553, causing the cysteine (C) at amino acid position 1518 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
